Hey people i'm on the look out for a e46 m3 but wanted to know the difference between a standard m3, SMG and CSL.

I know little things like CSL has no radio, slick tyres (bad in wet weather) a really weak and light floor pan (boot floor) etc. I would like to know more about the CSL features other then i've mentioned.

The SMG on the other hand i know nothing about...

ohh also i really like the yellow phoenix but something about it doesn't sit right with me... so i would like to know what colour you prefer....

Also please don't mention anything about convertibles as M3 were made to be driven not looked at.. Thanks.
