Dealer Add-Ons: Which Are Worth It and Which to Skip

Most dealer add-ons are optional, negotiable, and available elsewhere for less. A few are worth having in specific situations. The useful question for each one is not "is this a scam?" but "what problem does this solve, do I have that problem, and what is the cheapest way to solve it?"

The ground rules

They are optional. The Federal Trade Commission (FTC) describes add-ons as optional products and services, says you can usually buy the vehicle without any, and notes you can buy most of them from independent retailers.
They are not required for the loan. The Consumer Financial Protection Bureau (CFPB) says that generally you cannot be required to buy an extended warranty, GAP insurance, or credit insurance. If someone says a product is mandatory, ask them to show you where the contract requires it.
The price is negotiable. The CFPB says so directly.
Financing them costs extra. Anything rolled into the loan increases the amount financed and the interest you pay.
Many can be canceled. The CFPB says you have the right to cancel optional add-on products and may be due a refund if you sell, refinance, or pay off the loan early. Physical items installed on the car are different.

Why dealers sell them: these products are a meaningful source of dealership income, and the people who sell them are often paid on what they sell. That is an incentive, not a character flaw. It does mean the pitch will be good.

Add-ons at a glance

No prices are listed here because they vary widely by dealer and product. Get a written quote and compare it with the alternative.

Add-on	What it is	When it can make sense	Typical alternative
GAP (guaranteed asset protection)	Covers the difference between your loan balance and what your insurer pays if the car is totaled or stolen	Small down payment, long loan, rolled-in negative equity, or a lease that does not include it	Your own auto insurer or your lender; compare prices and coverage
Service contract ("extended warranty")	A promise to pay for certain repairs after the factory warranty	You plan to keep the car long past warranty and a large repair bill would be a real hardship	Buy later, before the factory warranty ends; manufacturer-backed plans from any franchised dealer of that brand; a repair savings fund
Prepaid maintenance	Pays up front for scheduled services	The price is below what the same services cost individually, and you will use that dealer	Pay as you go; check whether the brand already includes free maintenance
Tire-and-wheel protection	Covers tire and wheel damage from road hazards	Low-profile tires or expensive wheels on rough roads	Road hazard coverage from a tire shop; setting money aside
Paint and fabric protection	A sealant or coating applied by the dealer, sometimes with a limited warranty	Rarely, at dealer pricing	Do it yourself, or hire an independent detailer
VIN etching	The vehicle identification number etched into the glass as a theft deterrent	Rarely, at dealer pricing	A do-it-yourself kit; ask your insurer whether it earns any discount first
Nitrogen in tires	Tires filled with nitrogen instead of ordinary air	Not at a charge	Check tire pressure monthly with regular air
Theft-deterrent or tracking systems	An alarm, tracker, or recovery service, often pre-installed	You want the specific service and would pay for it anyway	The car's built-in connected services; an aftermarket tracker
Key replacement	Covers lost or damaged key fobs	Fobs for your model are costly and you tend to lose things	Check your insurance and roadside coverage; price a spare fob
Credit life and disability insurance	Pays the loan if you die or become disabled	Seldom the most economical way to get this protection	Term life or disability insurance that covers more than one debt
Accessories (mats, wheel locks, tint, pinstripes)	Physical items added by the dealer	You want the item and the price is fair	Buy the same item online or from the parts counter

The ones that deserve a closer look

GAP

Standard auto insurance pays what the car is worth when it is totaled, not what you owe. If you owe more, you pay the difference. The CFPB describes GAP as an optional product meant to cover that shortfall.

You likely do not need it if you made a sizable down payment, have a short loan, or already have equity. You may want it if you put little down, financed for 72 months or more, or rolled a previous loan's balance into this one. See negative equity.

Before buying it at the dealer:

Ask your auto insurer and your lender for a price. The CFPB notes they may offer it and that costs vary widely.
Check whether your lease already includes it.
Read the limits. Some contracts cap the payout or exclude certain amounts.
If you are told it is required for approval, the CFPB says its cost must then be included in the finance charge and APR. Ask to see that in writing.

Service contracts

The FTC is clear that a service contract is not a warranty, even when it is called an extended warranty. Before buying one, ask who backs it (the manufacturer or a third party), what is excluded, what the deductible is, where repairs can be done, and what the cancellation terms are. You rarely need to decide on the day you buy the car. Our guide to extended warranties and service contracts goes deeper, and new car warranty explained covers what you already have.

Prepaid maintenance

This one is simple arithmetic. Ask the service department for the price of each scheduled service in the plan, add them up, and compare with the plan's price. Remember that a financed plan also carries interest, and that the plan has no value if you move away or sell early unless it is transferable or refundable.

Pre-installed add-ons

Sometimes the product is already on the car: etched glass, nitrogen, a coating, a tracker, wheel locks. The dealer may say it cannot be removed, so you must pay.

Your options:

Ask before you visit. In your price request, write: "Please list any dealer-installed accessories or packages and their prices." See how to read a dealer listing.
Decline to pay for it. "I understand it is already installed. I didn't ask for it and I'm not paying extra for it." Many dealers will reduce or remove the charge.
Negotiate the total. If the line stays, ask for the same amount off the vehicle price.
Buy elsewhere. Another dealer may have the same car without the package.

The FTC has taken action against dealers that charged for add-ons customers had not agreed to or falsely said they were required. Its advice to buyers: confirm the contract matches what you agreed to, ask about any fee you do not recognize, and be willing to walk away.

What to say in the finance office

A short script, repeated as needed:

Thank you. I'm going to pass on all optional products today. Please print the contract with just the car, tax, and required fees.

If you are interested in one product:

Can you give me the price, the term, and the contract for that one in writing? I'd like to compare it before I decide.

And if a product is presented as a monthly amount:

What is the total price of that product, not the change in my payment?

A few dollars a month over a long loan is a large number. Always convert it back to the total.

Before you sign, check that the contract's itemization lists only the products you chose, each at the total price you were quoted, and that you have the actual contract for each one. For where these lines appear on the paperwork, see how to read a buyer's order. For the meeting itself, see the finance office: what to expect.
