    Re: {full_name} v. CarGurus, Inc.

    Dear {full_name}:

    This Attorney-Client Agreement (“Agreement”) outlines the nature of our engagement, along with our mutual responsibilities and expectations. Kindly take a moment to carefully review this letter and feel free to contact us if you have any questions or require additional clarification.

    Scope of the Engagement: This Agreement is between Milberg, LLC (the “Firm”, “We”, “Us”) and you (“Client” or “You”) for the purpose of legal representation in connection with your potential claims against CarGurus, Inc. its affiliates, and/or any other responsible parties (collectively, “Respondents” or “CarGurus, Inc.”), arising from alleged violations of the California Invasion of Privacy Act (CIPA). 

    This representation covers investigation and, if appropriate, pursuing the claims described above. It does not include any other actual or potential causes of action, appeals, or legal services arising from this or any other matter. After this engagement concludes, the Firm will have no further obligation to advise or provide any legal services on your behalf, unless agreed in writing. You expressly authorize the Firm to discuss your account and obtain your account records from Respondent. Client further represents to the Firm that Client has not signed an agreement with any other attorney(s) to pursue claims against Respondent(s).

    Arbitration and Consolidation. Arbitration is a simplified means of pursuing legal claims, where disputes are resolved by a neutral arbitrator instead of a judge or jury, discovery is more limited, and the arbitrator’s decision is subject to limited court review. While we anticipate arbitration, this Agreement remains in effect regardless of whether the claims are ultimately brought in arbitration, litigated in court, or resolved by settlement before any formal filing. By signing this Agreement, You provide us with a limited, enduring power of attorney to sign legal documents that are related to the arbitration, litigation, or settlement of the claims described above, on your behalf. You or We may terminate this limited, enduring power of attorney by terminating this representation, as described below.

    Express Settlement Authority: You give us exclusive authorization to negotiate settlements with the Respondents, including as part of a group settlement with other similar claims, and to make decisions about litigation or settlement tactics on your behalf. You give us the right to reject any settlement offer that is not equal to your actual loss, or the maximum allowable damages, whichever is greater, unless we believe that we have achieved the likely best settlement possible under the circumstances. If we bring you a settlement offer from the Respondents or about your claim, the final decision on whether to accept the offer is yours. However, we may advise you that we feel the settlement is fair and reasonable, and if you disagree with our advice, we may withdraw as counsel after giving you reasonable notice or ask the arbitral panel for permission to withdraw as your attorneys consistent with the applicable ethics rules. 

    Attorney’s Fees & Costs: You won’t owe us any fees unless we successfully collect a financial recovery for you by payment of an award or settlement of your claim. We agree to represent You on a contingency basis, which means that our fees are a percentage of the settlement, award, or recovery, or other monetary benefit You receive. In the event your claim settles or results in a recovery or award, our fee will be forty percent (40%) of the total gross recovery obtained on Your behalf, unless an arbitrator or court awards a higher fee, in which case the higher amount will apply. If there is no recovery, You owe no fees or costs. 

    After our fees are deducted, we deduct expenses from your gross recovery. Expenses can include expenses specific to your individual arbitration or expenses that we advance on behalf of all our clients with similar cases for the benefit of the whole group of clients. These expenses may include our usual and customary fees for copying, messenger services and similar items, as well as travel expenses. Additionally, to improve efficiency and lower costs, the Firm may use AI-driven solutions for select tasks, e.g. fact investigations, document review, and other routine activities, under the supervision of licensed attorneys, while taking reasonable steps to safeguard client confidentiality. Expenses that we pay to vendors, arbitrators, experts, or others who assist in the arbitration claim process are not kept by us and are billed at cost. Once there is a recovery, settlement, or judgment in your favor, we will inform you in writing of the amount of expenses to be deducted from your award and the nature of the expense.

    If there is recovery or settlement in this case, you grant us the right to receive any monies resulting therefrom, deduct fees and expenses, and send you the remainder. We will do so as soon as practicable. If we cannot locate you or an authorized representative within 90 days of receipt of the funds, we may either hold such funds in escrow or deposit them with the court. In the event you do not elect how to receive your settlement award, you agree that we may disburse your funds as an electronic debit/credit card to the email address we have on file. You understand that we may have a lien upon any amount recovered for you.

    You acknowledge that we may associate with other counsel in connection with your claim, in which event we will split our attorney’s fee with co-counsel. It will not increase your overall fee obligation. 

    Cooperation: You agree to fully assist and cooperate with us regarding your case. You agree to be truthful and to promptly, accurately, and completely provide us with all relevant facts, preserving all pertinent evidence, and being available for discussions, meetings, and any required court or arbitration proceedings. The representations by Client in the Certification below are material terms of this Agreement.

    Consent to Joint Representation and Collective Proceedings: You understand and acknowledge that the Firm represents other clients with similar claims against the same Respondent(s). By jointly representing multiple clients, the Firm can pool resources and potentially offer a more effective overall strategy; however, this approach may not maximize your individual share of any recovery. The Firm will not favor one client’s interest over another. Client further understands that some settlements may be conditioned upon a certain percentage of participants agreeing to resolve their claims through settlement. You understand and acknowledge these benefits and risks, consent to the Firm’s joint representation of you alongside other similarly situated clients and waive any conflicts that might arise from such representation. Accordingly, you authorize the Firm to pursue your case in individual, multi-party, collective, representative, or mass arbitration or court proceedings, and to negotiate classwide, collective, mass, coordinated, or representative settlements of claims.

    Communications and Confidentiality: You have certain responsibilities as a client, including the responsibility to keep us updated as to your contact information, to promptly respond to our communications, and provide information and documents we need for your claim electronically. Email will be our primary means of communicating with you. It is your duty to keep your contact information up to date and promptly inform us of any changes to personal information. You may receive text messages from us or on our behalf in connection with providing our services to you. All communications and case-related information must be kept strictly confidential. This includes refraining from sharing any information on social media or public platforms.

    Termination of the Representation: You have the right to end this Agreement at any time, provided you give the Firm timely written notice. Similarly, the Firm reserves the right to terminate our representation for good cause, including but not limited to, your failure to comply with this Agreement, lack of cooperation, refusal to follow our substantive advice, if continuing to represent you would be unlawful, unethical, ineffective, if there is little or no likelihood of success on the claims’ merits, if continued representation would result in an unreasonable financial burden, or for any other reason that is permissible under relevant professional or ethical guidelines.

    Arbitration between You and Us. The relationship between You and Us will be governed by New York law, without regard to its conflict of law rules. Any disputes between You and Us will be decided in arbitration by the JAMS, under its Streamlined Rules, which can be found here: https://www.jamsadr.com/rules-streamlined-arbitration/, in your county of residence or in New York County, unless the dispute is subject to arbitration under the Part 137 Fee Dispute Resolution program. More information about that program is available here: https://ww2.nycourts.gov/rules/chiefadmin/137.shtml. 

    Entire Agreement: This Agreement constitutes the sole and entire agreement between the Firm and You and supersedes all prior and contemporaneous understandings, agreements, representations, and warranties, both written and oral, with respect to the subject matter. If any term or provision of this Agreement is invalid, illegal, or unenforceable in any jurisdiction, it shall not affect any other term or provision of this Agreement or in any other jurisdiction. 

    Acknowledgment and Agreement: Client hereby acknowledges having read and fully understanding the terms of this Agreement and having had opportunity to seek independent legal advice before signing this document. 

    If You agree with the outlined terms, we kindly ask that you sign and return this document to indicate your agreement. We look forward to working with you and advocating on your behalf in this matter.

    Sincerely,

    /s/ Douglas H. Sanders

    Re: Notice of Dispute Concerning Violations of the California Invasion of Privacy Act

    To Whom It May Concern:

    I hereby provide notice of my individual dispute with CarGurus, Inc., together with its subsidiaries, affiliates, vendors, partners, agents, service providers, and related entities (collectively, “CarGurus”), arising from my use of CarGurus.com and CarGurus’s use of code or similar software processes to (a) collect or transmit non-content routing, addressing, signaling, or similar information, and (b) intercept, disclose, use, procure, assist, or facilitate third-party access to information associated with my electronic communications with CarGurus and activity on CarGurus.com, without my prior informed consent or legal authorization.

    Nature and Basis of Dispute

    I personally used CarGurus.com while I was physically located in {answer_2}. I used cargurus.com to  {answer_4}, or engage in other transaction- or account-related activity. To the best of my recollection, I did so during approximately the past {answer_3} before this Notice.

    Based on technical investigation of CarGurus.com, and unbeknownst to me at the time, CarGurus configured CarGurus.com to invoke, deploy, or cause the execution of TikTok-related code, including the _ttp cookie and related software processes (collectively, the “TikTok Tracking Tools”). When I accessed or interacted with CarGurus.com, CarGurus’s website code caused the TikTok Tracking Tools to load, execute, set or read identifiers, and transmit network requests from my browser or device. Those tools caused my browser or device to collect, record, capture, transmit, disclose, or make available to TikTok, ByteDance, and/or related third parties non-content routing, addressing, signaling, source-identifying, device-identifying, session-identifying, cookie-identifying, timestamp, IP address, user-agent, browser/device, PageView, and event-metadata information associated with my CarGurus.com communications and activity (the “Non-Content Tracking Data”). Separately, and in the alternative, some information captured, transmitted, disclosed, or made available through the TikTok Tracking Tools also included or revealed the contents, substance, or meaning of my communications and activity on CarGurus.com, including page URLs, referrers, search or ZIP-code parameters, vehicle-listing activity, click events, and “Get Prequalified” interactions, to the extent those data points reflected what I searched, viewed, selected, clicked, or communicated while using CarGurus.com (the “Content-Revealing Data”). I refer to the Non-Content Tracking Data and the Content-Revealing Data together as my “CarGurus Communications and Tracking Data.”

    The TikTok Tracking Tools were not limited to a single page or isolated interaction. Technical testing showed that they loaded across multiple tested portions of CarGurus.com, including the homepage, a reload of the homepage, vehicle-category pages, vehicle-listing pages, and search-results pages.

    This information matters because my activity on CarGurus.com reflected vehicle-shopping communications and intent, not random web traffic. It could reveal the vehicles or types of vehicles I searched for, viewed, compared, selected, or clicked; the ZIP codes or locations where I was shopping; the pages or listings I interacted with; the timing and sequence of my activity; and whether I engaged with financing-related features, including the “Get Prequalified” interaction. Combined with TikTok cookie identifiers, IP address information, user-agent/browser/device information, timestamps, URLs, referrers, and event data, this information could allow TikTok, ByteDance, or related third parties to recognize, distinguish, associate, profile, or retarget my browser, device, session, location, vehicle interests, and financing-interest signals.

    To the extent CarGurus contends that its terms of use, privacy notice, cookie disclosures, banners, or other notices authorized this conduct, I dispute that. My ordinary use of CarGurus.com was not informed, prior, or specific consent for CarGurus to install, embed, deploy, configure, use, or cause the operation of the TikTok Tracking Tools on my browser or device as a pen register, trap-and-trace device, or similar software process. Nor was my ordinary use of CarGurus.com informed, prior, specific, or all-party consent for CarGurus to permit, assist, facilitate, or cause TikTok, ByteDance, or any related third-party vendor to receive, intercept, read, attempt to learn, disclose, use, or make available the contents, substance, or meaning of my communications with CarGurus.com.

    As a result of CarGurus’s conduct, I lost control over information concerning me and was deprived of the ability to make an informed privacy choice. This supports claims under federal and state privacy, electronic-surveillance, and anti-wiretapping laws, including the California Invasion of Privacy Act, Penal Code §§ 638.51, 631(a), and 637.2. The same conduct also supports claims under applicable consumer-protection laws, including laws prohibiting unfair, unlawful, or deceptive acts or practices, as well as statutory and common-law privacy remedies available under applicable law.

    Relief Sought

    I seek a good-faith informal resolution of my individual dispute. My requested relief includes all statutory, actual, equitable, injunctive, declaratory, restitutionary, disgorgement, and other relief available under federal and state law.

    For purposes of informal resolution, my good-faith calculation is at least $5,000 under California Penal Code § 637.2 for CarGurus’s violation of CIPA § 638.51, subject to supplementation based on records showing additional violations or separate actionable conduct. To the extent CarGurus’s conduct also violated CIPA § 631(a), including by causing, permitting, assisting, or facilitating TikTok, ByteDance, or related third parties in receiving, learning, using, or obtaining Content-Revealing Data, I seek all statutory damages available under § 637.2 for those violations as well. Because the precise number of violations depends on records in CarGurus’s, TikTok’s, ByteDance’s, and related vendors’ possession, I reserve the right to supplement this demand and damages calculation after those records are provided. I also seek disgorgement, restitution, or other monetary relief to the extent available; and appropriate injunctive and equitable relief requiring CarGurus to stop any unlawful interception, pen-register, trap-and-trace, TikTok pixel, cookie, or similar tracking practices as to me, and to delete and refrain from using, selling, sharing, disclosing, or retaining any unlawfully collected CarGurus Communications and Tracking Data associated with me, except to the extent preservation is required for this dispute or by law.

    I ask that CarGurus preserve all records relevant to my claim and provide sufficient information for my counsel and me to evaluate an informal resolution. I authorize CarGurus to communicate with my counsel identified below regarding this dispute and to disclose to my counsel records and information concerning my account or associated with my use of CarGurus.com that are reasonably necessary to identify my relevant interactions, determine what tracking technologies were active during those interactions, evaluate what information was collected or transmitted, calculate relief, and discuss informal resolution.

    Request for Informal / Pre-Arbitration Resolution

    I am providing this Notice in good faith before initiating formal proceedings to afford CarGurus an opportunity to discuss an informal resolution of my dispute. If this dispute is not resolved informally within 60 days after this Notice is received, I intend to pursue my rights in any available forum and through any available procedure, including individual arbitration before the American Arbitration Association. (CarGurus, Inc., Terms and Conditions of Use (last updated Apr. 10, 2026), https://www.cargurus.com/about/terms-of-use.) In doing so, I expressly reserve all arguments and objections to the validity, enforceability, applicability, interpretation, effect, or satisfaction of any CarGurus arbitration, waiver, limitation, forum, governing-law, mass-arbitration, public-injunction, unilateral-modification, informal-resolution, condition-precedent, or dispute-resolution provision, including objections concerning formation, assent, notice, scope, delegation, unconscionability, waiver, fees, costs, limitations periods, venue, arbitral rules, public injunctive relief, representative relief, and consistency with applicable law. I also reject, and do not consent to, any unilateral modification of CarGurus’s terms, privacy policy, or any other purportedly applicable terms unless I affirmatively agree in a separate signed writing.

    This Notice is not a complete statement of all facts, claims, legal theories, damages, remedies, defenses, responses, objections, or grounds. I reserve the right to amend, supplement, refine, or expand this Notice and my requested relief based on additional information, CarGurus’s records, vendor records, arbitration, litigation, discovery, motion practice, expert analysis, or further investigation. I reserve all rights, claims, remedies, arguments, and objections.

    This Notice concerns only my individual dispute with CarGurus. I have personally reviewed this claim and, based on my current understanding and the information available to me, believe it is factually supported, not frivolous, and not duplicative.

    Please confirm receipt of this Notice and direct all communications regarding this dispute to my counsel listed below.
