Favorite has to be the 850csi. I still drool at the sight of the old 8 series. I had a N55 135i M sport with the DCT trans. Man that car was a ton of fun to drive, I would usually beat e90 m3s in autocross when I went out, and the thing just ripped. I have an on ramp that is about a half mile straight before getting to the highway and I could get the 135 close to 150mph on it. The saturn would top around 130, though supposedly objectively as fast.

Unfortunately it spent 2 out of the 10 months I owned it in the shop, all electronics issues. Dimming rear mirror went, Idrive and the whole center console crapped out (that was a month or so of it), which required replacement of all center display units and control modules, the dct module, and reflash of just about all the others. It also died while driving randomly on me one day which required a battery replacement (wtf?) and things like the lumbar support kept deflating, etc. Warranty covered the repairs, but I dumped it and lost a ton of money. No prior repairs/accidents and PPI was clean, who knows. I loved to drive it but jeez was it stupidly expensive to own.
