This is regarded by many as the best BMW ever created. And this one is one of the very best out there. Not only is it in pristine condition but it also has a few key upgrades which really help enhance the character of the car. The only question is…Should I buy it?

The video takes us through the process of building one of the best M cars BMW has ever done: The E39 M5. The 30 minutes long footage focuses on the exterior and interior design of the E39 M5, on its engine and suspension engineering, and finishes with a few minutes of car porn at the legendary Nurburgring race track.
