1957 Morgan Plus 4 2+2. Blue with red interior. Introduced at the 1950 Earl’s Court Motor Show, the Morgan Plus Four was a lengthened version of Morgan’s first four-wheel car, the 4-4, aimed to be a more luxurious and advanced car, featuring hydraulic brakes and Morgan’s Sliding Pillar front suspension. In 1953, the original 2-liter Vanguard inline four was traded for the engine from the Triumph TR3 and in 1954, it gained its now-iconic domed, vertical bar grille.
