I raced an M3 at the Pod two years ago, back to back three times.
In all three races, it was soooooo close - all 13.7/13.8s
Not quite sure why people slate the M3 so much though? Sure, it has the BMW badge, but it's one of the best balanced chassis for a road car available.
And what's all this "you'll destroy it" nonsense. 2/10s of a second is fook all. That's the equivalent of saying that you just thrashed the opposition football team 1-0
