Also... I think all of the current M cars are solid. There is definitely some cheapness going on and a lot of weight bloating but they are still some of the best cars you can buy.
What does get me is the BS marketing... the M sport cars are not M cars however it seems BMW has really stepped their game up on the M performance cars and really hasn't progressed the actual M cars much at all.
Case in point... look at brand new X3 M40i vs X3M comp... both pretty much look identical right now... the M comp has a slightly better suspension and more power... great... tune the B58 and ur awfully close.
