Since earlier models of Peterbilt and Kenworth companies appear to maintain their value, it is possible to approve older trucks in general. Keep in mind that we are basing our decision on the worth of the truck, and not the credit score of the buyer, thus the age of the truck will have an effect on its value. However, the less money we're willing to lend to a customer whose truck is more than ten years old, the better off they'll be.
