Well, it depends on what you are talking about regarding the comparo. Does a Cadillac compare to a Bimmer? It depends on what you consider important. If you consider praise from the car rag idiots to be important, you can't go wrong with any BMW. I recall an article on BMW's active steering in the 5-series. They wrote about how the system kept getting wildly out of whack and they'd have to shut the car down and restart it. And about how it would change ratios through turns and such and they'd almost crash, and then proceeded to praise it for being so direct and "real".
The Aurora is FWD. FWD V8's are not that common, but they will get a bit more so soon. GM has put the Chevy smallblock in FWD configuration now, and will show up on Impala/Monte SS's as well as the Grand Prix GXP.
I think I now own one of every family of GM DOHC V8. At least I can't recall any others in modern history.
