To BMW or not to BMW, that is the question !

[SamN01]

Basicaly I have seen a Z3M Roadster (The 2 door model) for sale at a very good price £18k for a 98/R and I am very tempted. The one thing that bothers me is I hear the ride is not to great is this true ??
My last car was a 450 Chimp how would the to cars compare ??

Thanks for your help.
