A service contract quote is a sales document. It usually shows a price, a term, and a few headline features, and it is written to move you toward the signing step. It is not always the contract, and the gap between the two is where many buyers get surprised.
Find out how long the quote holds
Look for a line that says how long the offer stands. Some quotes carry an expiry, and some are tied to the vehicle's current mileage or age at the time they were produced. If the quote lapses, the price you were shown may not be available again, even from the same company. Write the expiry in your own notes, and ask the seller what happens if you need a few extra days to decide.
Separate what is locked from what is estimated
Ask which parts of the quote are fixed in the contract and which are only estimates. Inputs such as mileage, vehicle age, and term length may be recorded at the quote stage and then checked again at signing. If the details on the form differ from the details you were given, stop and ask why before you initial anything.
Ask what the quote leaves out
A quote rarely lists every limit, condition, or waiting rule. Ask for the full form the quote refers to, and ask the seller to show you the page that covers each thing the quote mentions. Anything the seller describes that you cannot find in the form is not part of your agreement yet. Ask for it to be added in writing, or leave it out of your decision.
Check payment and cancellation before the quote becomes a deal
Read how the amount is paid, whether it is paid up front or folded into a loan, and what the cancellation section says. A quote may describe a refund in a single sentence, while the form sets out the calculation in detail. Use the form, not the quote, to decide.
Where to look next
Some companies post a sample contract you can read before you ask for a quote. That lets you check the wording against the quote you were given. This site lists those companies on its page of providers that publish a sample contract. For the published terms themselves, use the comparison tables here rather than relying on what any one salesperson tells you.
