The state of Maine states :
What are ‘Program Cars’?
Usually a Program Car is a used car that was probably used as a daily rental car. Generally, a program car is no more than 2 years old and has the remainder of the factory warranty available to the next owner. A factory warranty is a warranty provided by the car manufacturer that covers the repair of certain parts and vehicle defects. Generally it will provide coverage for a certain number of years or miles, whichever comes first.
Also, with having the car being a program, as opposed to a used car, the car will be better taken care of, and should have less miles on it than if it was used. (This part is YMMV.) My main issue is the savings right off the front end regarding tthe price of the car, which can add up to serious money in the subsequent time involved. Alas, if you also throw in a higher interest rate for the program car, this can vary.
(Also known as, run the numbers before you walk in, so you know how much you are willing to pay for the particular vehicle, and if you have to finance it, how much you are willing to pay per month, and how long you are willing to let the bank own it before you do.)
