an N/A then move up to a TT. You will learn a lot from the NA. I understand he doesn't have much experience with the Z's yet so I think a N/A is ok to start out with. The TT will him a lot more trouble than a N/A ever would. However I 100% agree that the TT is way funner to drive Im sure. I've had my N/A now for about 6 years now (since highschool)and I love it. It has been a very reliable car (ofcourse thats if you do your maintance on it). I haven't moved up to a TT yet cause I do not have a garage yet so MAKE SURE YOU HAVE A GARAGE just to work on your Z. I have been told that for a while now and I finally agree. Anyways Good luck with the Z.
