2007 BMW M5 Sedan 4dr Sedan (5.0L 10cyl 7AM)
Not up to BMW M standards
 Too heavy, not a precise and agile M car as its forebears were. Most of the performance is completely unusable in daily driving. Prepare to be beat at every stoplight unless you are really on it.  I think J. Clarkson said it best: completely annoying until you hit the M button. Too bad you can't use that button for 95% of your driving; meaning you will have a really annoying car for 95% of the time you are driving. Sold mine a bought Porsche: a massive improvement in just about every way.
