9. Mercedes CLK GTR
In the late 1990s, Mercedes was on the wings of success and enjoying its new-found performance image, courtesy of AMG. With their market success came the need for racing, so Mercedes set its sights on the legendary 24 Hours of Le Mans race. To participate in the 1997 Le Mans 24h, Mercedes needed a car and that was AMG`s task.
Soon, AMG prepared a fully operational prototype with a 6.9-liter V12, highly sophisticated mechanics, and an aerodynamic package. According to the rules, Mercedes had to build at least 25 road-going versions before it was free to race. So, AMG produced 20 coupes and six roadsters all with a race-prepared 612 HP V12 engine in the back.
The cost of new CLK GTR was over 1.5 million dollars, which earned it the title of the world’s most expensive passenger car in 1998. Unfortunately, the CLK GTR was not successful in racing. So, soon they canceled the racing car class and the car became obsolete, but it’s still a highly valued collector’s item.
