I'm in Indy... on the east side, in Irvington. I sport a carbon black '06 M3. Haven't been able to get up to C and C or Paradise Cafe since I bought the car in April but I keep crossing my fingers I'll get a chance. I've been too busy using the comfortable hours on Saturdays to do maintenance on the car...
I can second the good work that Vaughn does but it's sooo far out of my way. I just had (a skipped by the previous owner) Inspection II done by Ress Motor Works in downtown Indy - great people. The valve adjustment was just under $400 - best price I found around here.
