The definition of a car with an identity crisis imo... Surely the CS and CSL badges are for the agile, nimble, smaller cars that might see some track action from time to time....not a 5 series. M5 Comp is a fantastic car and highly accomplished, but leave it there IMO . Why the need to keep using (and diluting) the meaning of a "clubsport" badge by sticking it on a 4 door family saloon? What next ? A Panamera RS / GT2 ? Perhaps I'm missing something, but I think I'd take an M5 Comp for family duties and a tricked up E46 for fun.
