Does anyone have any experience with how GM sells a car at the end of a lease? The residual on my car after 2 years is an amazing 20,400.00 which is why my payments are so crazy low. But it won't possibly be worth that much since they are only bringing high teens used now. Does GM offer to let you buy the car at market prices or do they always stick to the residual? If this turns out to be a good car, I might want to keep it- but not for 20,400.00!
