What's different about buying in Kentucky

Kentucky charges a 6% motor vehicle usage tax. Trade-in credit applies on new vehicle purchases — the rules have shifted over the years, so we verify the taxable base on every Kentucky deal sheet. Louisville and Lexington carry most of the state's inventory.

Trade-in mathYour trade-in's value is deducted from the purchase price before tax is calculated. A $15,000 trade saves you $900 in tax here — which usually makes trading in beat a private sale once you factor in the hassle.
