I loved my Supra TT6. I think the rear is still one of the best looking of any car on the road and think they have aged pretty well.
IMO the front is the only part of the car that looks dated, particularly the head lights. In the right colour (black) with the OEM body kit and lowered on a set of wheels, I would go as far to say they can even look classy as opposed to Chavy. I think the interior is far from dated and puts a lot of modern cars to shame.
Handling wise, they are much better than you'd think but maybe not quite as good as the Zed. A set of Tein or eibach springs, some yellow Bilstein shocks and replacing any worn bushes etc and jobs a good'n.
Engine wise, well not much needs to be said there, Twin Turbos, 400bhp very easily/cheaply done and as near to bullet proof as you could get.
