I was over on MBWorld for my stint with the C63, but havent been back since I put my deposit down on the M5 last May. I got a lot of useful info over there, but I agree, I felt the audiencce to be a bit immature or too old for my tastes. Perhaps it was because of the C63 crowd, perhaps not. I for one am glad Im back with BMW in this forum, as I used to chat frequently on M3 Forum when I had the e46.
I dont get the hate, just because you own one doesnt mean you have to dislike the other.
