The 1983 Mercedes-Benz 280 SEL represents the extended-chassis (Long Wheelbase) variant of the W126 series, specially designed to offer maximum space and comfort for rear passengers. This model, destined for the Swiss market, is powered by the legendary 2.8-liter (M110) engine with six in-line cylinders and two bump axles ( DOHC ). Due to the specific regulations of that time in Switzerland, this version produces 160 HP , slightly less than the European standard version, but maintains high refinement through the Bosch K-Jetronic injection system. With a 3075 mm wheelbase and a very quiet cabin, the 280 SEL remains the ideal choice for those seeking the prestige of a luxury limousine with an efficient and highly reliable engine.
