As per title really, would be interested to know about the best car you've ever owned. To my mind I think the Z4 has a pretty average build quality, every single one of them I've been in has some form of dashboard rattle....the new 3lt I bought in 2004 had it's dash replaced 3 times, but still didn't fix the problem. I think the chassis is too stiff for the cabin fixings, it jolts things loose eventually...
For me, the E46 CSL and especially the E39 530 I owned were by far away the best built cars I've had, nothing went wrong over the 3 years I had them, not a single squeak or rattle.
