OK where is all this TT info coming from guys. I'm all for this car as is and ready to buy as soon as I get back to Germany, but if there is solid info on an turbo charged V8 I'll be more than happy to wait for it.
Also, Eisenmann exhaust is absolutely a must have.
Got it on the 335i now and love it. I saw they were working on a sytem for the M3 and plan to add this as my first mod.
