I wish. It's got more carpark dings than any other car I've owned.
Depends if you mean build quality or reliability. And the V-8s are *much* worse reliability wise than the 6 cylinders.
Mine has had the famous heater motor resistor fail several times. I've only paid for one, though. Crank position sensor. Seized aux fan. Screen washer motor. That's it.
Never had one - I've only had 5 Series. E28, E34, E39. And it will probably stop there, as I don't much like the new one.
