Good question. Honestly, I prefer the 850CSi or the Alpina B12 5.0/5.7 Coupe.

That said the car is great with whatever engine. The V8 is much simpler, almost as fast, much more economical and if it came to a daily driver consideration I'd probably go for the 840Ci. Thing is that that only came with as an auto if I'm not mistaken.

Having a V12 6 speed manual as a daily I mean that's one great proposal to turn down :).
