?? are you saying the csl and e92 m3 lap times are rigged? but if you think about it, no offense to op as you want a 4 door, but if i were to spend that much $$ on a b7, i would def get a 06 competition and strip it out get the oem csl items i need, and build a na engine. ill be the first in the us and have a driving experience of my life
