In 1931 all Buick models were powered by an eight-cylinder engine. 1931 was the first year for the overhead valve, 'straight eight' engine. To highlight this fact, Buick placed the number '8' on the radiator cap. For 1931 Buick introduced the Series 50 which served as a replacement for the Marquette though it was mounted on the same 114-inch wheelbase. There were two series of the Series 8-50, with the first series beginning in July of 1930 and the second taking over in January of 1931. Standard equipment now included mechanical brakes, Delco-Remy ignition, and Hotchkiss drive with conventional transmission.
This is a Southern Ohio car that has only 50,400 original miles. The restoration was completed in 2002.
