2006 BMW M5 Sedan 4dr Sedan (5.0L 10cyl 7AM)
Best BMW Ever
 I recently purchased a 2006 M5 after retiring an Infiniti G35 and 2001 525i. In a nutshell, this car rocks!  It has all the features and benefits of a luxury car, yet when asked immediately this performs like a Formula 1 racecar.  Two thumbs up for BMW!!  If you can afford one, get one.  I promise you won't regret it.
