Kind of hard to compare that way. We're talking about BMW M and the M3 going back to 3.0 CSL (influence?) in the early 70's compared to quattro GmbH which only started producing S and RS models in the early 90's. So you can kind of see why some BMW enthusiasts might be a little annoyed with having the M3 becoming a M4 (coupe model), you're comparing 40+ years of M to a little over 10 years with the S and RS.
