1970 Mercedes-Benz 300SEL 6.3 Saloon


The 300 SEL 6.3 was Mercedes-Benz’s fastest and most opulent full-sized executive saloon car of the late 1960’s and early 70’s. The model started out as a private venture in 1966 by company engineer Erich Waxenberger, in what these days would probably be termed a “Skunkworks” project. His principle was simple: take the powerful 6.3-litre V8 from the luxurious 600 limousine, and squeeze it into the regular Mercedes-Benz S-Class model. The result was an almost 2 tonne saloon with performance similar to most dedicated sports cars of the era. Surprisingly, the rather conservative company went ahead and launched the car into the marketplace at the Geneva Motor Show in March 1968.


The 6.3-litre motor could catapult a car that weighed nearly two tonnes to a top speed of over 130mph and to 60mph from stationary in under seven seconds, respectable numbers for modern vehicles and an extraordinary feat for a luxury saloon in 1970. Adorned with the finest luxury fitments of the time, this was a car for those who were looking for the best in terms of automotive refinement.


This beautiful 1971 right hand drive 300 SEL 6.3 has undergone a detailed £61,000 restoration in more recent times. Any rust was removed, and the 6.3 was treated to new Mercedes inner and outer sills, followed by a bare metal refinish in Mid-Blue non-metallic paint. The engine was removed in order to detail the engine bay correctly, at the same time the power steering, brakes, air suspension and engine ancillaries were overhauled. Finally the interior was completely re-trimmed and woodwork/veneers refinished.


These 6.3-litre models offered class-leading levels of performance in their day and are the true forerunner of the AMG models which we are now familiar with. An exceptional example of a rare and desirable super-saloon.
