As you may already know I owned a 1990 na a while ago. I bought it when I was 17 and was happy as hell with it. At that time I didnt have the money for power mods or insurance for a tt. I had my car for over three years and loved it. I got compliments from everyone and tons of offers to buy it every where I went. Regardless of what anyone on this forum tells you a Z is Z, and whether you get a tt or an na just think about how much you would really be racing in it. Also consider how much you could race it if you ever got a ticket, could you still afford the car, and insurance? It costs more to maintain and upgrade a car you beat the crap out of. If you like the Z just buy one that you like whether it is a tt or not. If you get the na and aren't satisfied you could always sell it and look for a tt again, nothings final. This said I am currently looking for a good deal on a tt, and I know how you feel I almost cracked twice and got another na but they were both sold before I could look at them. If I find an na that I really like I would buy it in a heartbeat over waiting for a tt to come my way because I loved my Z and am positive I would love a new one just as much. Just think hard about your decision and dont buy one (especially off ebay) with out having it checked out first. Hope this helps-Pete
