At the desk you may be handed several documents in a short stretch of time, and many of them look official. Before you sign anything, sort them into their jobs. The manufacturer warranty came with the vehicle, the quote is a summary of an offer, and the service contract is the agreement you will live under if you buy it. Only the last of them answers the question you care about on the day a part stops working.
The warranty is not yours to choose
A manufacturer warranty is written by the company that built the vehicle. It is not sold to you at the finance office and it does not need your signature to exist. Read its coverage period and its exclusions so you know where it ends, and notice whether its limits are measured by time, by distance, or both. A service contract is a separate purchase with its own company, its own terms, and its own cancellation rules. Do not assume one speaks for the other, and do not let a salesperson's phrasing blur the line between them.
The quote is a sales summary
A quote is designed to make the offer easy to understand, which means it is often shorter than the contract and may leave out definitions. Ask whether the quote matches the signed form line by line. If anything you were told out loud is missing from the written paper, treat it as not part of your agreement until someone shows it to you in writing.
What the signed contract must answer
Look for these answers in the contract itself, not in the brochure. Who is the company that pays claims, and is it the same name that sold you the plan? Does the coverage list name the parts that are covered, or does it list the parts that are excluded? How does the contract define wear, and who decides whether a failure counts as wear? What are the claim steps, including whether you must call before a repair starts? How does cancellation work, how is any refund figured, and what happens to the contract if you sell the vehicle? If a sentence is unclear, write down the question and ask it before you sign.
Some providers post a sample contract you can read before you buy, which is the easiest way to check these answers. Our list of vehicle service contract companies that post a sample contract you can read first shows which ones do. Read the sample at home, not in the finance office.
Nothing on this page tells you what any particular contract will pay or refuse to pay. The contract you are offered is the only document that governs your claim, and it is worth reading slowly.
