Mercedes-Benz 300SEL

The Mercedes-Benz 300 SEL 6.3 started out as a private venture in 1966 by company engineer Erich Waxenberger, which culminated in the world's first "Super Saloon" or Q-car.



Surprisingly, the rather conservative company went ahead and launched the car into the marketplace at the Geneva Motor Show in March 1968, in order to make better use of the M100 engine production facilities. The 6,500 build of the 6.3 outnumbered the 2,700 build of the 600 by far.
