the m3 is built right in line with the F30 and F20 and Z4's. you see them about same frequency as any other time. if you are having an M3 built you can email the factory and arrange to follow only your car while its built. then you can spend all your time with the car you like. i bet if you ask them they probably arrange you to only look at m3's on the line.
"It gave you amazing satisfaction, but anyone who says he loved it is either a liar or he wasn't going fast enough." - Jackie Stewart on racing at the Nurburgring
