I mean, the M3 is probably a better car. Better built, engineered, it'll always start, won't go wrong but its german...and german cars are boring! Remember John Major on Spitting Image? Thats the kinda person who buys german!
They ain't all that! The only M3's worthy of the badge are the E30 and the E46....
Keep the Cossie and be an individual. Ok they're not bird pullers, but they sure turn a lot of heads! Guys mostly, but you might like that....
