You're asking a bunch of guys who's cars go into the red zone quite often and they are telling you not to trust the dealer's demo car????hmmmm If the car is going to have a warranty vs. you buying from a private owner like say... one of these guys with no warranty then maybe that demo is not such a bad idea after all...Remember, this is definitely one of the best cars out there especially as far as the engine is concerned, its like a duracell (think about it)
