What kind of car are you buying? It's difficult to "roll back" mileage on modern cars. I'm not saying it can't be done, but its not as easy as pulling the glass off and rolling it back with your finger like the old cars.
Suzuki Grand Vitara V6. Believe me bro, these guys are very resourceful here. If you know someone in the agency, you can get the change made without to much trouble.
