I would say to start PRICE!...you can do a nice replica GT for around $85 or so..correct me here if I am wrong guys.
Even though the new GT lists at $135 you aren't going to see it there for a while. The guess is $200 if you get one the first year and then who knows.
Personally I would love to have a new GT but I don't think it will be in my range for another 10 years....thats why I want one of the new Superformance GT40's and I can put a nice little 331 with webers in it
