Fun, but horrible for rough roads
 So, this is a screamer.  Everyone knows that.   We've had a really bad experience, however.   We've bent 7 wheels and replaced 4 tires due to impact damage.   The problem?  Well, we live in New England and our roads stink.   Huge seams where the roads are being repaved are very common.    I think maybe BMW didn't give the suspension enough travel or throw or whatever it's called because the shocks don't absorb the shocks on bad bumps and tire and wheel damage are frequent and hugely annoying.  If you do buy this car in the North East (I would NOT), be sure to buy from a dealer that offers wheel insurance.  Ours didn't.  And for BMW, the lousy thing is, no way out.  Can't get smaller wheels.
