The Buick Master Six was a series of passenger cars with a six-cylinder engine, which was manufactured by Buick in the model years 1925 to 1927 as the successor to the 24-Six series in the USA.

In 1928 the cars were given the suffix Series 120 based on the wheelbase in inches. The following year it was replaced by the Series 121 and Series 129 .

The new six-cylinder models for 1925 had an overhead valve engine with a displacement of 4178 cm ³ and a power of 70 HP (51 kW). The wheelbase of the cars with fourteen different two- and four-door bodies was 3,048 mm (cars with 2 to 5 seats) and 3,251 mm (cars with 7 seats). Their appearance was similar to that of their predecessors.

In the following year, the cars were slightly revised: the edges on the radiator were a little softer and the headlight inserts were now interchangeable. There was also a larger engine with 4,490 cm³ displacement and an output of 75 bhp (55 kW). The number of available bodies was reduced to thirteen (including a taxi ).

In 1927 there were no stylistic changes. There were only eleven bodies to choose from this year.

In three years, 308,694 Master Six were created.

In 1928, the previous year's model was adopted without major changes, but was given the addition of the 120 series , which referred to the (smaller) wheelbase. The stylistic changes were limited to the headlights, which were given a hemispherical housing instead of the drum shape that had been common up until then. Ten different bodies with two to four doors were offered.

This year 102,409 vehicles from the 120 series were built.

Series 121 and 129 (1929)

Wheelbase :	3073-3277 mm
Empty weight :	1719-1995 kg

In 1929 the series was completely revised by the General Motors Art & Color Department . The wheelbase grew by 1 "and the bodies got a bulge 40 mm below the belt line, which earned the series the unflattering name Pregnant Buick .

A convertible and the Pullman limousine, which was no longer manufactured in the previous year, were added and six different bodies with a short wheelbase (series 121) and eight different bodies with a long wheelbase (series 129) were offered. The name Master Six was omitted. The six-cylinder engine, which now drew 91 hp (67 kW) from a displacement of 5,073 cm³, had grown significantly.

The changes were obviously not recognized by the public, because this year only 61,893 short-wheelbase and 26,390 long-wheelbase units were built from the large six-cylinder.

From 1930, the 50 and 60 series replaced these cars.
