Get the GTO MR 6 speed
That way you don't have to worry about the active aero's, ecs suspension, adjustable exhaust and 4ws. The 6speed is the stronger box, watch out for 2nd gear crunch, quite normal and i've been quoted ~£500 to get sorted inc parts and labour.
That rules out 75% of the usual issues you get with these cars. + it looses quite a few pounds to the point were its not that bad weight wise (considering!).
Running costs, well i get 250miles to a tank. There are plenty of these cars being broken so spare parts are a plenty, and not that expensive if you know were to look. If your ok with a spanner and can follow a workshop manual they are not that hard to work on either!
Heres mine
Personally i think it looks as good as the supra, but without the scene tax (surely that bubble has to burst at some point!)
