For $25K I would go for a 01 onwards. The build quality is great. Gearbox is a drama if you want to dump it, having said that, one of mine had 175Kwatw and the box was fine. As for buying one with mods, I wouldn't let that be a factor, so long as it has been tuned for them, no dramas. The last one I sold had done 80,000kms+ and never had a cent spent on fixing anything. Diff between 01 and 02, is the gearing changed. 03>got sh*t interior. Having said that, I may be biased as I am purchasing another Sti. After driving around in AU Tickford Fairmont Ghia for the last month. I realised I wouldn't be able to overlook how second rate the Fords are, just because it has the potential to go quick in a straight line.
