Marquette

The 45 hp line consisted of one model only, the Model 28 7-passenger touring. It had a wheelbase of 119 inches, and sold for $4,000. ($138,214 in 2025 dollars

This reorganization was not successful, and GM announced the end of the Marquette in 1912. It appears that some of the last pre-war Marquettes were labeled "Peninsular". The plant then closed in 1913. During World War I, the plant was reopened and used to manufacture mortar shells for the US Ordnance Corps, then was repurposed for engine block casting when operations at Northway Motor and Manufacturing Division ended in 1925. The factory was repurposed as Chevrolet Saginaw Parts Plant which made many different types of parts and closed in 1983 and was demolished in 1984. Located on corner of 6th & Washington Avenues.

Buick brand

The Marquette nameplate was revived when the Buick division of General Motors launched their junior brand for model year 1930. Along with Viking, LaSalle, and Pontiac, the Marquette was conceived to span a price gap in General Motors' market segmentation plan, and shared the GM B platform with the Buick Standard Six and Buick Master Six. Marquette was placed below Buick, but above Viking which was to be sold in Oldsmobile dealerships. The Marquette arrived in dealer showrooms on June 1, 1929.

The Marquette line rode on an 114 in (2,896 mm) wheelbase and was powered by an L-head straight six 212.8 cu in (3.5 L) producing 67 hp (50 kW) which was uncharacteristic of Buick products using overhead valves. Marquette was built to sell in the $1,000 range, and was available in a single car range. This Series 30 consisted of six body styles:

Model 30 Two-Door Sedan

Model 34 Sport Roadster

Model 35 Phaeton

Model 36 Business Coupe (2 pass.)

Model 36S Special Coupe (2/4 pass.)

Model 37 Sedan

The Marquette's most distinctive styling feature was its herringbone grille. Reviewers at the time described it either looking like a small Oldsmobile or small Cadillac.

Compared to Oldsmobile's Viking, which enjoyed a total production run of only 7,224 over three model years (1929, 1930, 1931) Marquette produced 35,007 vehicles in the U.S. during its brief one year life span; additionally, GM Canada turned out another 6,535 Marquettes.

Despite its promising first year sales, two factors worked against the Marquette. The first involved Oldsmobile, which lost sales to Marquette; the second was that Buick executives did not feel that enough Marquettes were sold to warrant the extra burden on the bottom line given the state of the economy. Buick gave no advance warning of the termination of the Marquette; just four months before the shutdown, 4,000 Marquette signs were shipped to dealers in the hope of better days ahead. The entry-level position held by Marquette was replaced by the new entry-level Buick Special.

After the shutdown of Marquette, the engine production tools were shipped to Germany, where it was used to power the original Opel Blitz. This was the first link between Opel and Buick, a sporadic tie-up which was to last until General Motors finally severed ties with Opel in the 21st century.
