Not having looked into the M3 too much before I got mine, I never realised about the E46.

Wether by luck or judgement (the first one I'm sure) Thats what I have just bought!

I don't know if another number in my cars description is important or not?

The full spec is : E46 M3 Coupe S54 3.2. Is there any relevance on the S54 part?
