A dealer’s used-car Buyers Guide should state whether the vehicle is sold as is or with a warranty and what share of covered repair costs the dealer will pay. Compare the final Guide with the sales contract and every written promise before signing. An independent inspection and vehicle history report still matter because a warranty can exclude the problem you later face.
Used-car buyers often discover an expensive defect after purchase and remember a salesperson saying the dealer would take care of it. The useful evidence is the final Buyers Guide and written promise, not memory alone.
Start here: a practical action plan
- Photograph the Guide and VIN.
- Order an independent inspection.
- Put every promise in writing.
- Follow repair authorization rules.
- Relying on a spoken promise.
- Treating a report as an inspection.
- Assuming a warranty covers every system.
Match the guide to the exact vehicle
Photograph the Buyers Guide on the vehicle and verify the VIN, stock number, mileage, warranty box, coverage duration, covered systems, deductible, and percentage the dealer pays. Obtain the final copy after the sale and compare it with the retail contract.
The FTC Used Car Rule requires covered dealers to display and provide the Guide. It distinguishes as-is sales from dealer warranties, but state implied-warranty rules and remedies can differ. The Guide does not replace a pre-purchase inspection.
Worked example: calculate the covered share
Example: a written dealer warranty covers 50% of a listed transmission repair during 30 days. An eligible repair invoice is $3,600 and the contract has no separate deductible. Dealer share is $3,600 x 50% = $1,800, leaving $1,800 for the buyer.
That example applies only if the failure, timing, facility, authorization, and repair are covered. If diagnostics cost $180 and are excluded, the buyer’s illustrative total becomes $1,980. Get a coverage decision before approving work.
| Hypothetical covered repair | Calculation | Amount |
|---|---|---|
| Eligible repair | $3,600 | Invoice |
| Dealer share | $3,600 x 50% | $1,800 |
| Buyer repair share | $3,600 - $1,800 | $1,800 |
| Excluded diagnostic | Buyer cost | $180 |
Put every promise into the final paperwork
Ask an independent mechanic to inspect the exact car, including codes, leaks, tires, brakes, structural evidence, and likely near-term maintenance. A clean history report cannot prove the present mechanical condition.
Write any repair, accessory, delivery, refund, or return promise into the purchase documents. If the Guide and sales contract conflict, do not sign until the dealer corrects both. Spoken assurances are difficult to enforce.
Use the inspection to price uncovered risk
After a failure, notify the warranty contact promptly and follow authorization rules. Preserve the Guide, inspection, diagnosis, photographs, estimates, and communications. Do not dismantle a covered component before learning whether inspection is required.
Budget the as-is vehicle from inspection findings plus a repair reserve, not only the payment. Insurance, registration, tires, deferred maintenance, and uncovered repairs can make a lower advertised price more expensive.
- Photograph the Guide and VIN.
- Order an independent inspection.
- Put all promises in writing.
- Follow warranty authorization before repair.
Frequently asked questions
Does as is mean I have no rights at all?
Not necessarily. Federal disclosure rules and state laws still apply, but an as-is sale can shift substantial repair risk to the buyer.
Does a history report replace an inspection?
No. It can reveal reported events, but it cannot verify the vehicle’s current mechanical condition.
What if the salesperson promised a repair?
Ask for the promise in the signed paperwork before buying. Preserve written messages if a dispute already exists.
Does a dealer warranty cover every repair?
No. Read the systems, time, mileage, percentage, deductible, exclusions, and authorization requirements.
Should the Buyers Guide come with the car?
Covered dealers must give the buyer the final Guide after the sale, including qualifying online sales.
Can I return a used car within three days?
Federal law does not create a general three-day cancellation right for dealer car sales. Check the written return policy and state law.
