Mercedes-Benz Luxury LWB (W109)

The W109 extended the W108's luxury formula on a longer wheelbase — and then rewrote the rules entirely when Erich Waxenberger installed the 600's M100 6.3-liter V8 in a formal saloon body.

Most W109s were long-wheelbase six- and eight-cylinder models — the alloy-block 300 SEL, the 2.8 that replaced it, the 3.5 V8 that outsold every other version, and the North American 4.5 — aimed at owners who wanted rear-seat space and chauffeur duty without stepping up to the hand-built W100. The 300 SEL 6.3 was something else: a Q-car capable of genuine supercar pace in a three-box suit.

Production over 1966–1972 came to 23,550 cars.
