Calculating a refund under the Florida Lemon Law is very straightforward. You are entitled to what you put into your vehicle, including sales tax, finance interest, and other collateral charges added by the dealer less an offset for your use of the vehicle. The offset for your use is calculated by taking the vehicle’s purchase price and dividing that number by 120,000. This figure will tell you the per mile charge you will be assessed. The per mile charge is then multiplied by the number of miles driven up to the point that your case goes through arbitration, which is a pre-requisite before filing a legal complaint in a court of law. Should you not prevail at arbitration and your case goes into court, the mileage offset does not change. In other words, you will not be penalized for additional miles driven after arbitration.
