Some say the BMW M3 is one of the most desirable car ever. Each generation had its fans, but almost all of them are in love with the M3 CSL, with its lovely raw and shrill noise of the six-in-line engine. The sound of the CSL is one in a million. After that, the V8-powered M3 was introduced, which sounds great too, but not as great as the CSL. With the coming of the M4 Coupé this sound will somewhat return, but will it equal the CSL? To make us up, Auto Leitner putted four generations next to each other, which resulted in some beautiful footage!
