Model History

The W112 300 SE Cabriolet was unveiled alongside its Coupé counterpart at the 32nd Geneva Motor Show in March 1962. These two-door four-seater cars were the result of Mercedes’ consistent combination of technical brilliance, impressive performance and elegant design. As the last of the great six-cylinder, two-door Mercedes, the 300 SE of the 1960s represented the German manufacturer’s unrivaled efforts to produce the best handcrafted luxury automobile possible, using only the finest materials and workmanship.

In terms of their style, both coupé and cabriolet were based on the respective variants of the W111 220 SE. The full-length floor unit was adopted from the tailfin saloon, underscoring the stately presence of both two-door vehicles with their 2.75m wheelbase and overall length of 4.88m. However, these new models did feature trim elements in addition to those of the 2.2-litre cars, as well as being equipped with the engine and technology of the 300 SE saloon. Initially, the M189 IV straight-six cylinder light-alloy engine delivered 160hp at 5000rpm, having an increased output of 170hp at 5400rpm from 1964 onwards. Depending on the rear-axle ratio and the engine installed, coupé and cabriolet could reach top speeds of between 108mph and 121mph.

Standard equipment included a four-speed automatic transmission, power steering, pneumatic suspension, and a dual-circuit brake system with disc brakes all round. The additional chrome decoration consisted of a continuous trim strip in the longitudinal groove running from the headlamps to the tail lights, and distinctive trim strips on the front and rear wheel arches. In March 1963 a 4-speed manual transmission became available, and January 1964 brought the replacement of the injection system by a 6-plunger injection pump, which increased the engine’s output by 10hp to 170hp.

Production of the 300 SE Cabriolet and 300 SE Coupé was discontinued in December 1967. Over six years of production, only 708 Cabriolets emerged from Sindelfingen, and just 92 of these were in right-hand drive. The example featured here is, therefore, the most exclusive of that series.

This gorgeous W112 300 SE is one of just 92 cabriolets produced in right-hand drive. The car is finished in its original colour combo of Dark Green with contrasting Parchment leather upholstery. The paintwork is very presentable all round having been refreshed in the past, with few signs of age or wear to speak of. There are no unsightly scuffs or scrapes to the glossy finish, and all items of trim are present and correct. Some patination to the chrome is visible upon close inspection but generally a mirror shine is retained. All badges, headlamps and taillights look in particularly fine fettle, and the original black soft-top is present without any damage.

The Mercedes appears in excellent driver-quality condition overall, offering a tremendous base for further restorative work should the new keeper desire. Having seen little use under current ownership some re-commissioning will be required if it is to see regular use.


The interior is lavishly upholstered in Parchment leather with glamorous walnut trim adorning the dash fascia, instrument cluster, and A pillars. The front seats are some of the most comfortable you will find in a car of this vintage, and despite showing signs of age there is no damage to report; the rear seats remain in excellent unworn condition, as do the door panels and armrests. Edged in leather the carpets are in fine order throughout.

Glancing across the dash you’ll find the steering wheel looking fresh, the supple leather trim free of any cracks, and the original Becker radio system still in place. A really nice touch is the accompanying Becker documentation, which includes warranty cards for both the Grand Prix and Reims units. At the rear of the car the rubber mat is in great original condition having never gone brittle, and the boot floor remains solid.


As a 1964 300 SE this example boasts raised compression and a larger Bosch injection pump than pre ’64 cars, resulting in an increase in performance from 160hp to 170hp. Under the bonnet the original "matching number" 3-litre straight six appears in good order. The engine feels strong on test and with almost undetectable gear changes the car is an absolute pleasure to drive.


The Mercedes sits on 14-inch wheels with body-coloured chrome hubcaps. Each of the wheel trims present well with a bright polished finish to each rim. The wheels are wrapped in a matching set of whitewall tyres, as per original factory specification. Out on the road the disc brakes remain feeling sharp, and the smooth pneumatic suspension operates exactly as intended.
