Model history:
The 1960s were some of the best years in the post-war period for Germany. The economic boom was phenomenal and many luxury goods were produced, including many in the automotive industry.
Derived from the famous «Heckflosse» (the four-door luxury-class sedan introduced in 1959), with the internal designation W111, Mercedes-Benz presented a coupé on February 24, 1961 and the convertible in September 1961. Both were equipped with a 2.2 litre engine (model 220). In September 1965, the models 250 SE Coupé and Cabriolet came out with the 150 hp Mercedes-Benz M129 engine of the W108 series. Like the three-litre models, they received 14-inch wheels and the larger-sized disc brakes of the luxury sedans, now with disc brakes on the rear wheels. These models are known to insiders as «high coolers». The 250 series was built until December 1967 and then replaced by the 280 SE with a 3.5 litre engine under the type designation 280 SE 3.5. Because of adjustments to the body and the front radiator grille with a lower overall height, they are also known as «flat radiators». At the same time, the 300 SE (W112), also known as the SEL with air suspension, was built from February 1961 to July 1965.
