Z4M Coupe or Roadster? How to choose?

[tikamak]

I got a nice comment today from a buddy of mine on his first ride in the M Roadster:

him: " you want to supercharge that ?"
me: " yes probably, after i have done suspension brakes, diff and exhaust"
him: " don't do that man, it will be really hard to control"
me : " why ? it will be like your dinan stage 3 e46 m3"
him: " your car is on steroids right now ..."
me: " hehe ye thanks"

irrelevant to wether you should choose the roadster or the coupe. i just felt like sharing :P
