Most accurate trade in value for cars
For example, if you buy a $10,000 car and the trade-in value is $5000, then you would only be required to pay sales tax on $5000. Depending on the rate of sales tax in your area, this could save you anywhere from 4% to 10%. Just think of the sales tax savings as an added bonus. Start by accurately pricing your trade-in with a tool, such as NerdWallet’s car value estimator, which uses pricing data from the National Automobile Dealers Association, or NADA.
