There is nothing wrong with buying a demo. I work at a VERY large dealership which sells Porsche,Mercedes,Jaguar,VW,Mazda,Dodge,Buick,Chrysler and Jeep and there is alot of salesmen and other people who drive different demo's about every 3,000 miles and i know them all pretty well and they treat the car like they were driving someone else's car.(its not theirs anyways lol) None of these guys whip the cars. Look at it this way....no break-in period and the car is still under warranty of course. So no biggie, if something goes wrongs with your car which i don't think it will the warranty will cover it with only under 3500 miles. I would buy a demo in a heartbeat! Go for it dude!
