I can never get near the 17 and 25 my car was quoted it feels more like 12 and 19. Also eventhough the XFire is a nice touring car and very capable of making the trip I would consider another vehicle due to the NO SPARE issue. That Tire Kit crap is just that CRAP, i got a flat on the rear wide tire on a trip from Miami to Orlando and was it a headache, no one had the tire in stock right then and there it would have to be ordered and if they did they wanted like $400 for a tire which is crazy, so reconsider and take another vehicle and put the beating and miles on a rental not your XFIre.
