It's the dream for nearly every human being on this earth: striking it rich. If you weren't born into a wealthy family, then becoming rich is likely a goal. For those lucky few who do, there's often one car brand and one specific letter they're attracted to: BMW and M.

Powered by a twin-turbo V8 with 560 hp and 502 lb-ft, the current F10 M5 is the most powerful and fuel efficient of its kind to date. It's also the most refined M5 ever, but is it too tame for the true enthusiast that has the means to stump up the heftty $90k base price?
