Is there a cooling-off period after buying a car?

What federal law says

The FTC’s used-car guidance is direct: “Federal law doesn’t require dealers to give you three days to cancel the deal and return the car” (FTC). It goes on: “In some states, dealers must give you the right to cancel. In other states, the right to return the car in a few days for a refund exists only if the dealer chooses to offer this option.” Before you buy, the FTC suggests you “ask about the dealer’s return policy, get it in writing, and read it carefully.”

What the FTC’s Cooling-Off Rule covers

The Cooling-Off Rule “gives you three days to cancel certain sales made at your home, workplace, or dormitory, or at a seller’s temporary location, like a hotel or motel room, convention center, fairground, or restaurant” (FTC). The rule itself, 16 CFR Part 429, applies to a “door-to-door sale”: one in which “the seller or his representative personally solicits the sale” and “the buyer’s agreement or offer to purchase is made at a place other than the place of business of the seller,” for $25 or more at your home or $130 or more somewhere else (16 CFR 429.0(a)). In a covered sale, the seller has to tell you that you may cancel “at any time prior to midnight of the third business day after the date of this transaction” (16 CFR 429.1).

Two parts of the rule leave out sales by car dealers:

• Deals negotiated at the dealership. The rule’s definition doesn’t include a sale made “pursuant to prior negotiations in the course of a visit by the buyer to a retail business establishment having a fixed permanent location where the goods are exhibited or the services are offered for sale on a continuing basis” (16 CFR 429.0(a)(1)).
• Cars sold at temporary locations. “The requirements of this part do not apply for sellers of automobiles, vans, trucks or other motor vehicles sold at auctions, tent sales or other temporary places of business, provided that the seller is a seller of vehicles with a permanent place of business” (16 CFR 429.3(a)).

The FTC also lists sales “made entirely online, by mail, or telephone” among those the rule doesn’t cover (FTC).

Where you may still have time

• State law. Some states require a right to cancel (FTC). California now does for many used cars (see the state notes).
• The dealer’s own policy. If a dealer offers a return window, its terms set the days, miles and fees. The FTC suggests you ask about the policy, get it in writing and read it carefully (FTC).
• The products sold with the car. The CFPB says that if you add an optional product to your loan, “you have the right to cancel it during the term of the loan” (CFPB). See Can I cancel GAP or an extended warranty after I buy a car?
• Financing that wasn’t final. If you took the car before the loan was approved, the CFPB notes that a clause in “many contracts allows the dealer to renegotiate the deal after you drive the car off the lot,” and you aren’t required to agree to different financing (CFPB). See Can a dealer change the deal after I drive home?

Without one of these, your chance to ask questions comes before you sign. How to ask for the out-the-door price shows how to get the total in writing, and the out-the-door calculator adds it up.
