I have owned 2 sapph cossies,and have recently bought an e36 m3 evo.
I am now looking for another cossie as the beemer promised so much,but i am a little underwhelmed by it. It is very fast,but the brakes are shite,and the offset pedals are hardwork. It is definately NOT the ultimate driving machine. It has leather,climate control,cruise control etc.,but it is missing that buzz you only get with a cossie.
I feel instantly at home in any sierra though,having owned at least 20 of them,so my view is not totally unbiased!
