How Does a Car Trade-In Work?

A car trade-in is the process of giving your previous car to a car dealer while buying a new car in return for a discount on the price. The specifics of carrying out a trade-in will vary by the practices of the dealership and the exact situation, but most trade-ins involve negotiations over the value of the existing car that happen before the finalizing of the offer the buyer makes for the new car.

Blue Book Value

An individual car's "Blue Book value" is often the starting point behind negotiations. Blue Book values are a database of accepted values for different cars of different years, amounts of mileage, features and other things, and thus make a good general estimate of the worth of a car. Blue Book values for used cars usually have a "trade-in value" as well as a private sale value, meaning the value is what the consumer should expect from a trade-in or a private sale. Informed consumers should research the Blue Book values of their cars before attempting to use the car as a trade-in, because a dealership may attempt to offer less than the car is actually worth as a way to maximize their own profits. In addition, knowing the Blue Book value helps customers to keep realistic expectations of what they will get from a trade-in so as to not be overly optimistic. Note that some trade-in cars will not be able to fetch their estimated Blue Book values during a trade-in, such as if the car is not running or if there is obvious damage or repair work needed.

Making the Offer

Once a consumer knows a car's trade-in value, the consumer is able to go to a dealership offering a car for trade. The consumer establishes contact with a sales representative and indicates interest in the new car and offers up the specifics of the trade-in car. The sales representative uses a computerized system to calculate an "offer" for the trade-in car that is usually a stipulation that the offer will become a discount from the consumer's intended purchase of a new car. (Most dealerships will not buy cars directly from consumers without making the exchange as a part of a sale, although some will.) The consumer can then attempt to negotiate for a higher amount on the trade-in if the consumer feels that the trade-in offer was too low. This may succeed if the dealership is especially eager to make the sale of the new car that would result from working out a deal on the trade-in, but if the dealership is not hurting for sales or feels that the consumer is being unreasonable, it may hold fast to its original offer for the trade-in car.

The Actual Trade-In

Once the two parties have come to an agreement about the value of the trade-in car and the sale price of the new vehicle with respect to the trade-in car, the consumer completes any paperwork for the new vehicle as with any car sale and then takes possession of the new car while the dealership takes possession of the trade-in car. The title of the trade-in car is transferred to the dealership, and the dealership may then sell the trade-in car to another dealership or may prep it for sale themselves as a used car.
