Head over to http://www.supraforums.com.au/forum/ thats where you will get good answers, but let me give you a briefing. An NA supra is very decent, i just got one myself a month ago, you get decent power coming from the inline 6 engine. Although the TT is in a class of its own. The SZ model is the non-turbo and the RZ is the Twin Turbo model. Supras (Mark IV) began production in 1993. In 1996 they got a make over with black headlights, and greyish tailights. And some minor interior adjustments as well. In 1997 they introduced VVTi to the 2JZs. I just got a recently imported one for $18k driveaway. A clean white supra with stock bodykit.
