Mercedes-Benz Executive Sedan · Typ 350
A large six for the late 1920s boardroom.

The Typ 350's generous dimensions and powerful inline-six suited long-wheelbase saloons, landaulets and open touring cars aimed at captains of industry and senior government officials. It represented the upper tier of Mercedes-Benz's six-cylinder range before the straight-eight Nürburg and the Kompressor sports cars defined the extremes of the catalogue.
Between 1928 and 1929, 713 examples were built — a modest count that reflects the car's exclusive clientele and the narrow window before eight-cylinder luxury and supercharged sport models reshaped Mercedes-Benz's top end.

1 distinct series across 1928–1929 — each identified by its chassis and engine numbers from period factory data.
