I found my M3 quite boring compared to my Stage3 Cossie but the M3 was the better car by far. The M3 never went wrong in 2 yrs,just main dealer servicing

I wouldn't hesitate to buy another E36 M3,the early ones are such a lot of car for about 5-6k & mine still felt tight at 120k miles, the build quality of an M3 is a million times better than a Sierra Cosworth. Trouble is a stage 3 cossie is more fun to drive
