I personally wouldn’t buy any BMW other than an M3 or M5 for the simple fact that you can get the same elsewhere (the 5-series and 7-series both have ‘worthy’ [if you will] competitors). However, after owning my M, I am never going down from this level of car again. A G sedan, Maxima, 3-series/5-series are just too small for me now. M56 or LS is definitely in my future.
