The sedan had four doors, the coupé only had two seats and there were two additional models, a 4-door touring car (E-49) and a 4-door sedan (E-50) with seven seats each. The wheelbase of the 2- and 5-seater was extended by 3 ", the 7-seater had a 9" longer wheelbase.

In 1919 the four-cylinder series was discontinued, so that the six-cylinder mid-range models were Buick's only offer. There were still the six models from the previous year without major changes, now with the serial number H-Six. There were no significant changes in the two following years either. The series were called K-Six and 21-Six.

Buick Model 22-54 (1922)

From 1922 onwards, the six-cylinder engine was again replaced by a four-cylinder series. There were still the six models from the previous year. There were also three new models, a seven-seater Pullman sedan with four doors (22-50L), a three-seater sports roadster with two doors (22-54) and a four-seater sports tourer with two doors (22-55). While all other models still had wooden-spoke wheels, the two sports models had wire-spoke wheels.

The Pullman limousine was discontinued in 1923, but the new model was a five-seat touring limousine (with a separate trunk) with 4 doors (23-41). The bodies have been redesigned a bit. So the front fenders were turned inwards and the bowl-shaped headlights gave way to cylindrical specimens.

73,307 six-cylinder Buick were built in 1922, and 112,258 in 1923.
