I think it is exactly as fast as an e46 M3.
With 350hp and 330ft-lbs it seems like a really sweet engine.
this is one of those moments that even if you can afford the car you really have to look at parts prices cause even if you are a good mechanic (jlee,Manimal,Fuzzydunlop,myself) along those lines. you have to look at parts prices cause i know anything AMG commands a really good price tag! its the reason i wont buy one because 1500 for a coil pack set *which you have to buy all of cause there linked* is just to much for me its the reason i wont buy one. but they are very pretty cars!
