How long is a car price quote good for?

It depends on the dealer, and many quotes are short, sometimes a few days or until the vehicle sells. Incentives often change at the start of a month, which can affect new car quotes. Ask directly how long the quote is valid and get the expiration in writing alongside the itemized numbers. OffLot's Open lot mode includes "how long is this price good for?" as one of its questions to ask at the dealership.
