I agree with Trisk on this one. Your not going to get much of a skyline for 5k, and at that they are big buses! Supra is again a complete bus, and you'll need to buy one for about 8k to be quicker. M3, again heavy things, but are quick when modified. But if you go down to your local circuit, 106 gti's are doing these on track! Subaru, horrible car. And slow... until modified heavily. Evo, nice car, but running costs are hugeeee. I don't consider many cars to be an upgrade from a well specced starlet. There have been lots of people that have sold up their starlet and gone for a 200sx or something, and regretted selling up! Although i can understand people preferring rwd for the fun factor but you'll soon get bored of buying new tyres
