I have a 1991 stage 7 TT that I have had no issues with since I have purchased it....It is incrediably fast and is loads of fun to drive. I have a close friend with a 03 350Z and it is really a lot of sports car for the money. Having driven both of them I can say that the TT is by far the most responsive and seems to have more more comfort features as per the interior. The 350z on the other hand has an ultra modern look that i really think is sharp and performance wise for a n/a is a real screamer.The interior has the look of new age sport cars.To be totally honest ....I wish I had both of them.....love all Zs.......
