How long are you planning on keeping the vehicle? How many miles will you drive it per year? Do you keep a car spotless?
I've never tired it. I keep my cars way too long for it to make any sesne for me. But I' have heard lots of horror stories about unexpected costs when one tries to turn it back in. Horrendous charges for over mileage, disagreement and chages about overall condition. and the deck is stacked in the dealer's favor. I will be watching this thread for more opinions.
