3,499-cc, 197-hp single OHC V-8 engine, four-speed manual transmission, double wishbone coil-spring independent front suspension, swing axle coil spring independent rear suspension, and four-wheel power-assisted hydraulic disc brakes. Wheelbase: 108.3-inches

Mercedes’ W108 and 109 models were the large luxury line of 1965–1972, replacing the Heckflosse or “Fintail” W111/112 cars. They initially used the venerable overhead-cam straight six in several sizes, all the way up to 2,996 cubic centimeters, and the cars’ nomenclatures were 250S, 250SE and 300SE, depending on the engine. A 2,778 cubic centimeter “M13” engine in 1967 gave rise to 280S and 280SE model designations. By 1969, however, it was recognized that the lack of a V-8 was a hindrance in the U.S. market, so a 3.5-liter powerplant, designated M116, was developed. Using a cast iron block for rigidity, economy and better sound damping, it had cross-flow wedge cylinder heads with rocker-operated valves driven by a single overhead camshaft per bank. Cams were chain-driven for a long life. Bosch transistorized the ignition, and electronic fuel-injection was utilized. The British magazine AutoCar called it “a copybook example of how experience plus careful design can create a simple-to-make high output engine of considerable refinement.” Initially with 3,499 cubic centimeter displacement, it was followed by a 4,520-cubic centimeter “big block” M117 version in 1971.

In Mercedes’ sometimes confusing nomenclature, the new W108 model was designated 280SE 3.5, to distinguish it from its six-cylinder counterpart. Production began in August 1969 and continued through July 1971. Total production in 24 months was 3,270 coupes and 1,232 cabriolets. The 1971–1972 cars with the larger engine were designated 280SE 4.5.

This example is a very rare European-spec 1971 280SE 3.5 Coupe with only 51,325 original miles. These Grand Touring coupes are not only beautiful, but thanks to the 3.5-liter V-8, it travels the road effortlessly. This particular Mercedes features two options: the incredibly rare four-speed manual transmission (believed to be one of only 122 built with this option), and also sunroof delete.

It is presented in excellent overall condition with the Red perforated leather interior being original, never dyed and in remarkable condition. The body was repainted, with the engine out, in its original Alpine White color in 2008. It also had an original-style air conditioning system installed by the dealer when delivered new in Italy. Even though the Interior is 100-percent original, the leather is as soft and supple as when new. The car also carries its original Becker AM/FM radio and VDO Kienzle dash clock. The wood dash accents are refinished to as-new condition. This Mercedes-Benz comes with documentation and service records that date back to 1983, and it also has a copy of the original build sheet. The car received a major service in November 2012 in which over $5,000 dollars was spent. The car also has new Michelin Harmony tires. This car was also shown at the 2009 Hillsborough Concours d’ Elegance in Northern California; further testament to its overall condition.

Comparatively rare as Mercedes-Benz cars go, the 280SE 3.5 has a distinctive niche in the collector car community.
