I've always loved the look of the '95 to '99 M3, though I've never driven one. Nowadays you can get 'em for around $18K, so I'm wondering if I should get one to accompany my '01 M5. Do you think I will be utterly disappointed with 240 hp after driving a M5, or will I think it's tons of fun to drive? Should I pay more for a chipped or supercharged car? Any advice from those who know both cars?
