A warranty is a promise from the seller or manufacturer about the car's condition, while a service contract is usually a separate paid agreement to repair or replace specified parts for a fee, and mixing those labels on a used-car deal is how buyers overpay for coverage that excludes the failure they later have. Federal warranty law defines both ideas in 15 U.S.C. 2301, and the FTC Used Car Rule still requires a clear Buyers Guide under 16 CFR 455.2.
Warranty in plain terms
A written warranty says the warrantor will fix or replace covered defects for a stated time or mileage. On a used car it may be a short dealer warranty or leftover factory coverage. Read who pays for diagnosis, towing and related damage. Our extended warranty guide covers common paid products sold as warranties.
Service contract in plain terms
A service contract sells repair coverage for a price, often through a third-party administrator. It can be declined. The exclusions, waiting periods, tear-down fees and cancellation refund rules matter more than the brochure. Our service contract guide walks through those clauses.
Why the label changes your rights
Under 15 U.S.C. 2308, a dealer that sells you a service contract at the sale or within 90 days cannot disclaim implied warranties on the car. A pure as-is sale without a written warranty or service contract usually does disclaim them where state law allows. Our as-is disclaimer limits guide covers state limits.
Financed add-ons
If the contract is rolled into the loan, you pay interest on it. Compare the cash price of the contract with the coverage term, and ask for a cancellation refund schedule. Our payment packing guide shows how add-ons inflate the amount financed.
How to choose
If the car is still under a transferable factory warranty, you may not need a third-party contract. If the car is as is and high-mile, a contract only helps if the covered parts match the real failure risk and the administrator is easy to claim against. Get the full contract, not a summary, before you say yes.
Questions before you buy a contract
- Is this a warranty from the seller, or a third-party service contract?
- What parts and labor are excluded?
- Is there a waiting period or a mileage deductible?
- Can I cancel for a refund if I pay the loan off early?
Reading the history report
Read the title section first: any salvage, rebuilt, flood or lemon brand changes the value more than anything else. Then line up the odometer readings by date and look for gaps or drops. Check the number of owners and the states where the car was registered. An approved NMVTIS check adds insurer and salvage-yard records. Our odometer discrepancy guide explains odd mileage entries.
Paperwork to keep
Keep the buyer's order, the retail installment contract, the odometer statement, any Buyers Guide, warranty or service-contract papers and every payoff or lien letter in one folder. Photograph the window sticker and the dash mileage on the day you sign. If a dispute comes up later, dated paperwork is what a lender, an insurer, a dealer licensing agency or a court will ask for first.
Compare the financing
Get a preapproval from a bank or credit union before you visit, so you can compare it with the dealer offer on the same term. Compare the APR, the amount financed and the total interest, not just the monthly payment. The CFPB auto loan tools walk through what to read on an offer. Decide on add-ons such as GAP and service contracts on their own merits, and get the price of each one in writing.
What the report costs
As of early November 2026 a CARFAX bought direct usually costs around $44.99, and AutoCheck sits a little lower. We are a licensed CARFAX and AutoCheck reseller, not affiliated with CARFAX, AutoCheck or Experian. Our guest price has been about $5.50 a report, about $4.50 for members, and about $6.75 for a CARFAX and AutoCheck bundle. Confirm the price at checkout, since it can change.
