This looks like racecar because it basically is one. But not quite. In order to qualify for the FIA GT Championship, a luxury car global racing competition, Mercedes-Benz had to sell at least 25 street-legal versions of whatever car it intended to run on the track. So Mercedes took the approach of designing a racecar first then delivering a small number of street-legal versions customers.
In this case, the street car is even more powerful than its racing sibling. Instead of the racer's 630 horsepower V12 this car got a 720 horsepower engine, making it one of only two cars to get that treatment.
Not only is this car one of just 25 ever built, it was the first of 25 ever built and it's only been driven about 1,300 miles. It has also been carefully maintained in its original condition. It even comes with a set of luggage, although the car has barely any storage space in which to fit it.
