American Motors introduced a completely restyled longer, lower, and wider Ambassador for the 1967 model year, now riding on a 118-inch (2,997 mm) wheelbase, or two inches (51 mm) longer than before. The Ambassador's platform was four inches (100 mm) longer than the new Rambler Rebel's 114-inch (2,896 mm) wheelbase. The Ambassador was positioned in the standard-size category, against traditional big cars such as Ford Galaxie, Chevrolet Impala, and Plymouth Fury. The convertible was offered again—this time in DPL trim—for 1967; but this would be the final year with 1,260 built. It featured an all-new "split stack" folding mechanism with concealed side rails that did not intrude into the backseat area, thus offering room for three adult passengers in the rear.
The car once again looked completely new, with a more rounded appearance that sported sweeping rooflines, "coke-bottle" fenders, greater glass area, and a recessed grille that bowed forward less than that of the 1965–66 models. Taillights were wider, rectangular, and divided by one central vertical bar. Motor Trend magazine described the all-new styling of the new Ambassador as “attractive” and “more graceful and easier on the eye in ’67.”
