GAP insurance and extended warranties at the dealer: what they are and what to ask

GAP coverage and service contracts are the two most common products added at the finance desk. What each one covers, how it shows up on the quote and in the loan, and the questions to ask before you sign.

Near the end of buying a car, usually when the financing is being arranged, you may be offered protection products. The two most common are GAP and a service contract, often called an extended warranty. Both are usually optional, both can add a lot to the amount you finance, and both are easier to think about calmly before you are at the desk.

We are not going to tell you whether to buy either. That depends on your car, your loan, your budget and what cover you already have. Here is what they are and what to ask.

GAP coverage

What it is. If your car is totaled or stolen, your auto insurance generally pays what the car is worth at that time. If you owe more on the loan than that, the difference is the "gap". GAP coverage is designed to pay that difference, subject to its terms.

When the gap is bigger. The gap tends to be larger when little was paid up front, when the loan is long, or when negative equity from a trade-in was rolled into the loan.

How it appears. As a line on the quote (GAP, GAP waiver, debt cancellation), usually included in the amount financed.

Questions to ask:

• "What exactly does this GAP cover, and what does it exclude, such as my insurance deductible?"
• "Is it required for this loan? If so, can you put that in writing?"
• "Is the price included in the amount financed? Will I pay interest on it?"
• "Can it be cancelled later, for example if I pay the loan off early, and is the refund prorated?"
• "Does my own auto insurer or lender offer similar cover?" (worth asking them directly too)

Service contracts ("extended warranties")

What it is. A contract that pays for certain repairs for a period of time or a number of miles. A manufacturer's warranty comes with a new car; a service contract is a separate product you buy. Some are backed by the manufacturer, some by third parties.

What varies. Which parts are covered, the deductible, where repairs can be done, whether you pay first and claim back, how long it lasts, and who backs it.

How it appears. As a line on the quote (service contract, vehicle service agreement, extended protection), usually included in the amount financed.

Questions to ask:

• "Who backs this contract: the manufacturer, the dealer or a third party?"
• "What is covered and what is excluded? Can I read the contract before I decide?"
• "What is the deductible, and where can repairs be done?"
• "When does it start and end, in time and miles? Does it overlap the factory warranty?"
• "Can it be cancelled, and is the refund prorated?"
• "Is the price included in the amount financed?"

Why the financing matters

When a product is added to the loan, you usually pay interest on it for the life of the loan, and the payment rises by a fraction of its price. Here is an example with made-up figures: adding $1,895 to a 72-month loan at 6.9% raises the payment by roughly $32 a month, which sounds small, but over 72 payments that is about $2,320 in total, including interest.

Always ask for the total of payments with and without a product, not only the change in the monthly payment. See amount financed vs out-the-door price.

Getting it in writing

Before you sign, make sure the quote or contract lists each product separately with its price, and that you have the cancellation terms. If a product was described as required, ask for that in writing too.

Check your quote

Upload the quote to Explain My Dealer Quote. It lists every add-on and protection product with the dealer's own label and price, explains what that kind of product usually is, gives you a question to ask about it, and shows the total of scheduled payments when the loan terms are complete. Draft My Reply can ask the dealer which products are optional, or ask for them to be removed.

Frequently asked questions

Is GAP insurance required when financing a car?

It is generally an optional product, but some lenders or leases include it or ask about it. If a dealer says it is required for your loan, ask for that in writing.

What is the difference between a warranty and an extended warranty?

A manufacturer's warranty comes with the car. An "extended warranty" sold at a dealer is usually a service contract: a separate product you pay for, with its own terms, coverage and backer.

Can I cancel GAP or an extended warranty after buying a car?

Many GAP and service contracts can be cancelled, often with a prorated refund, but the terms depend on the contract. Ask for the cancellation terms before you sign.

Should GAP and a service contract be in the amount financed?

They often are when you finance. That means you pay interest on them. Ask for the total of payments with and without each product before deciding.

Can I buy GAP or a service contract somewhere other than the dealer?

Often, yes. Some insurers, lenders and other providers offer similar products. Ask them directly so you can compare terms.
