Was planning to pick up an F80 M3 in a year or two also, but now with Gintani coming out with some TT kits, I'd say the chance is very slim, might go with a GT-R instead.
V8 TT with built engine is going to a game changer. For the mean time i am going to enjoy my SC'd M3 until i see what capable are those TT kits.
Good job Gintani
