2008 BMW M5 Sedan 4dr Sedan (5.0L 10cyl 7AM)
What I expected
 Have had this vehicle 4 months now, so far very good experience.  My second BMW, both purchased new, and thus far more reliable that previous (X5); really no problems that have required dealer visit (after a few items that were resolved at 1200 mile oil change).  Great stealth car - looks much like "normal" 5 series to most, but really goes when challenged.  Good daily driver, with room for luggage and 4 adults, and makes to / from work or airport almost fun.  Sometimes tough to keep under speed limit - suggest a good radar detector, and set the speed limit warning because easy to go fast (set mine at 85).  Given other alternatives available today, would buy another if this one disappeared.
