Used Car Buyer’s Guide — Make the Dealer Put the Warranty Terms in Writing

What Is It?

FTC rules require many dealers to display and provide a Buyer’s Guide on used cars, and that guide can become powerful evidence about warranty promises and “as is” terms.

Do I Qualify?

  • You are dealing with a used-car dealer covered by the FTC Used Car Rule
  • The vehicle sale includes or should include a Buyer’s Guide
  • The problem involves warranty terms, “as is” language, or missing disclosures
  • You have the sales paperwork or photos of the window sticker

How To Use It

  1. Check whether the car had a Buyer’s Guide on the window before purchase.
  2. Save a copy of the guide and the final sales paperwork.
  3. Compare the guide to what the dealer promised verbally.
  4. Use the mismatch as leverage if the dealer later changes its story.

What Most People Don’t Know

  • The Buyer’s Guide can become strong evidence in a later dispute.
  • Verbal promises that conflict with the written guide are a warning sign.
  • A missing or altered guide is not a trivial paperwork issue.

Frequently Asked Questions

Is this automatic?


A: No. You have to save the guide and use it when the dispute happens.

What documents help most?


A: Photos of the window sticker, the Buyer’s Guide, repair records, and the sales contract are the best records.

Where do I start?


A: Start with the sales packet and any photo you took of the vehicle listing or window.

What is the biggest trap?


A: The biggest trap is letting the dealer keep all copies of the disclosure paperwork.
