There are few things cooler than a road-based sports car that has been converted to go off road. There are tons of lifted Mazda Miatas floating around the internet, but it's rare to see German sports cars that have been given the same treatment. Porsche famously raced rally-versions of its legendary 911 Coupe as far back as the 1960s, and since then, the idea has stuck. We recently featured a professionally built Nissan 370Z rally car, but this Safari-style 2007 BMW Z4 M Coupe is way more of an oddball, and thus way more interesting. Listed on Bring a Trailer, this blacked-out Bee-Em is looking for a new home, hopefully, close to a private rally track.

So what does it take to turn a Z4 M into a safari-spec rally racer? First, the suspension needs a good going over. The owner of this car fitted a Ground Control suspension setup which lifted the car by a good few inches, and then replaced the stock low-profile wheels with a set of 17-inch Black Rhino wheels with 235/65 Toyo Open Country all-terrain tires and a set of cross-drilled rotors.

The exterior is treated to a satin black paint job and highly modified fenders and bumpers. A 40-inch LED bar is an obligatory mod, as is the aggressive skid plate. The coolest exterior mod has to be the set of spare tires sticking out of the back.

The interior features the original black leather seats, side panels, carpeting, and even offers cruise control, navigation, and automatic climate control. There's also a 190 mph speedometer and a 9,000-rpm tachometer. The digital odometer shows 150K miles.

Under the hood, you'll find BMW's much-loved 3.2-liter S54 inline-six engine, which in the Z4 M produces 330 horsepower and 262 lb-ft at the crank. Power is sent to the rear wheels via a six-speed manual transmission and a limited-slip differential. The current owner has recently given this BMW a full fluid service. This awesome toy is sitting at $15K at the time of this writing. The auction ends on August 4 at 2:20 p.m.
