I am pro hockey player from Canada and I play down in the States. I am looking to buy another Z. I used to own an 04 roadster touring, but sold it. I found what looks to be a pretty nice 03 350z in Vegas with only 55,000miles on it, and a clean history. The thing is it's at a private dealership and they don't know anything about the cars. Wouldn't be much of a problem, but the car has what looks like a vortech Supercharger and an aftermarket exhaust, which I can't tell what brand from the pictures I've seen. Before I spend money on plane ticket to fly over there and drive it home, I want to make sure the car has been modified properly, and that the motor and tranny isn't beat up already. I want to tell them to take it to a shop to get it checked but I don't know where a good,reliable shop would be that would know what to look for with the supercharger. Can you point me in the right direction? I would really appreciate any help, so that I don't get burned by the dealer. You can PM me back or email me at horms12@hotmail.com, thanks, Barry.
