Powered by Mercedes-Benz’s venerable M 100 6.3-litre engine; the 300 SEL was certainly worthy of the three-pointed star. It was an engine born and bred on the racetrack, and is still considered one of the best Mercedes-Benz engines of all time. The 6.3-liter V-8 was able to get the substantial 300 SEL to a top speed of over 130 miles per hour and to 60 miles per hour in less than seven seconds, an extraordinary feat for a luxury sedan in 1970 and still noted as respectable today. Adored 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.

When first placed on the market, enthusiast magazines were anxious to test what was often billed at the "fastest production sedan ever built". At least one publication of the day, Road & Track, agreed with the factory's summation by saying it was "merely the greatest sedan in the world."

Mercedes-Benz has always been known for their interiors and the interior of this 6.3 certainly does not disappoint. The thick leather seats are of a quality that is far superior to anything that is offered today and they are in excellent condition. The original wood veneers have aged well and do not look as though they have been refinished. Many other aspects of the interior remain original, including the desirable Becker Mexico AM/FM radio with cassette. Additional equipment includes individual front seats, center console, factory air conditioning, rear speakers; power windows, steering and four-wheel disc brakes. Books and the tool kit are also included with the car.

Over $80,000 (verified by receipts) has been spent on this 6.3 in recent times, ensuring it is in excellent cosmetic and running order. Thirty-eight thousand dollars was spent overhauling the air suspension, injection pump, transmission and much more. All of the brightwork shines well and the paint has been professionally detailed, giving it a smooth surface throughout. Extensive service receipts, a factory tool kit, owner’s manual, factory suspension blocks, original steering wheel and horn pad.

Reports show that approximately 6,500 W109.018 Mercedes-Benz 300 SEL 6.3 Sedans were built during their December 1967 to September 1972 production run; another indication of the exclusive nature of this finely tuned German masterwork.
