The Buick Standard Six Series 20 was manufactured by Buick at what would later become known as the Buick City factory on Hamilton Ave. in Flint, Michigan, and was the junior model to the Buick Master Six between 1925 through 1929, and shared the GM A platform with Oldsmobile, Oakland and Chevrolet. The Standard Six evolved from the earlier Buick Six when the Buick 4-cylinder was cancelled. The Standard Six was the most popular Buick sold while being more upscale to the Oldsmobile Six. It was the senior brand to Marquette under the General Motors Companion Make Program until Marquette was cancelled one year later. It replaced the earlier Buick Six that was introduced in 1916, and was replaced with the Buick Series 50. Coachwork continued to be offered by Fisher Body who was the primary supplier of all GM products at this time, and Duco automotive lacquer paint, introduced by DuPont was the first quick drying multi-color line of nitrocellulose lacquers made especially for the automotive industry.
The Chevrolet Superior Series F was launched in 1923, manufactured by Chevrolet for four years with a different series per year. The 1923 model was known as the Series B, the 1924 model was the Series F, for 1925 it was known as the Series K and the 1926 Superior was known as the Series V. It was replaced in 1927 by the Series AA Capitol. It was the first Chevrolet that didn't have a larger companion model and was the only car sold by Chevrolet in several body style configurations all supplied by Fisher Body. Each year new mechanical changes, appearance updates or optional features that became standard in subsequent years became expected of all GM products including Chevrolet. Body styles were separated into open and closed which meant closed included retractable glass in the doors and glass surrounding rear seat passengers. Standard items included tools, a jack for tire removal, speedometer, outside lockable door handles, ammeter, oil pressure gauge, dashboard light, choke pull knob, electric horn, ignition theft lock, and a two piece vertical ventilating windshield that allowed fresh air to enter the passenger compartment. Wheels were 30" and came standard with hickory wood spokes or optional pressed steel discs. For 1925, bumpers were offered optionally along with outside side view mirrors, heater for passenger compartment and a clock.
The Buick Master Six, also denoted Series 40 and Series 50 based on the wheelbase used, was an automobile built by Buick from 1925 to 1928 and shared the GM B platform with the Oldsmobile Model 30. Previously, the company manufactured the Buick Six that used the overhead valve six-cylinder 242 cu in (4.0 L) engine in their high-end cars, and the Buick Four for smaller, less-expensive cars. After 1924, they dropped the four-cylinder engine and designed a small six, which they called the Buick Standard Six, to replace that end of the market. They coined the name "Master Six" for the high-end cars, now powered by the 255 cu in (4.2 L) engine released the year before. The yearly changes were a result of a new business philosophy called planned obsolescence.
The Chevrolet Series AC International is an American vehicle manufactured by Chevrolet in 1929 to replace the 1928 Series AB National. In all, 1,328,605 Series ACs were manufactured in a range of ten body styles, with 73,918 from Oshawa. The Series AC was distinguished from the AB by the introduction of a new six-cylinder engine, the first Chevrolet with a six-cylinder since the 1915 Chevrolet Series C Classic Six. Advertised as "A Six for the price of a Four", it was only $10 more than the outgoing four-cylinder Series AB. To simplify production operations, each factory was designated one body style for national consumption and shipped by railroad to major American cities. The serial number of origin was relocated to the right body sill underneath the rubber floormat except for the roadster and phaeton, which were inscribed on the right side of seat frame. Prices listed started at US$525 for the roadster or phaeton to US$725 for the Landau Convertible.
The Chevrolet Series FA of 1917–1918 is an American vehicle manufactured by GM's Chevrolet Division. It was a replacement of the Series F which had improvements in engine capacity as well as other features. In this transformation of series, the pre-existing names of the H and F series cars, The Royal Mail and Baby Grand were dropped in favor of the names Roadster and Touring respectively. The FA Series was then replaced by the Chevrolet Series FB in 1919. Production was not interrupted while the United States entered World War I starting in 1917.
The Buick 4 was a series of passenger cars produced by the Buick Division of GM from 1909 through 1918, and was available as a touring car, phaeton or roadster. It was available with the Buick Model B as a larger alternative offering a larger engine and better durability. It became the junior sedan in 1914 when the Buick Six was introduced.
The Oldsmobile Model 30, which continued to be known as the Oldsmobile Six, was built from the 1923 through 1927. Each year it was built, it was given the suffix 30-A, 30-B, 30-C, 30-D and 30-E for the last year of production, all having been manufactured in Lansing, Michigan. General Motors used the GM A platform, shared with the Buick Standard Six and the Oakland Six, and the yearly changes were the result of a new business philosophy called planned obsolescence. The Model 30 was Oldsmobile mid-level product and introduced the flathead Oldsmobile straight-6 engine, while the Oldsmobile Model 43 with a four-cylinder engine remained the entry level product. When the top level Oldsmobile Light Eight, with the flathead Oldsmobile V8 engine was cancelled in 1923, the Oldsmobile Six became the top level vehicle. It replaced the Oldsmobile Model 37 introduced in 1917, and was replaced by the Oldsmobile F-Series introduced in 1928. In 5 years, 236,474 cars were built. The growing popularity of GM's brands, like Oldsmobile, contributed to becoming the largest automobile manufacturer when sales overtook the Ford Motor Company during this time period. Coachwork for the various bodystyles were supplied by Fisher Body of Detroit, MI, and starting with the 1923 model year, all GM products adopted a shared appearance, with brand specific unique appearance features. The retail price had dropped considerably from previous years due to the popularity and affordability of the Ford Model T, with the top level sedan at US$1,095.
The Chevrolet Series F of 1917 was an American automobile manufactured by Chevrolet before they became a division of General Motors. The successor of the Series H, it had a longer wheelbase and other improvements, but kept the same engine. It was replaced the following year by the Series FA in 1918, which had a larger, more powerful engine. It was sold as the larger alternative to the Chevrolet Series 490, and the Model F was available for US$800 as either a roadster or touring sedan. As the Model F and Series 490 were in direct competition with the Ford Model T, sales were recorded at 110,839 for Chevrolet, with 57,692 Series 490 and 3,493 Model F. Chevrolet instituted Knock-down kit assembly where the product was created at Flint Assembly, then shipped by rail to the branch locations and locally assembled using locally sourced items such as tires, glass and other items. In 1917, the Monroe Motor Company was sold to William Small of Flint MI and was no longer sold by independent Chevrolet dealers when they weren't part of GM. Mason Motor Company was merged into Chevrolet once it became a division of GM and was used to supply engines for GM-Chevrolet vehicles.

It was offered as a replacement to the Oldsmobile Curved Dash runabout when it was discontinued in 1908, and was the junior platform to the Oldsmobile Six introduced in 1913. GM had acquired Elmore Manufacturing Company, Oldsmobile and Oakland Motor Car Company in 1908 and Cartercar and Rainier Motor Car Company in 1909 as their entry-level models, and Oldsmobile products were being repositioned in their new hierarchy as GM began to consolidate operations after William Durant had left.

It replaced the Model 42 also known as the "Baby Olds", while the most significant improvement was a longer wheelbase shared with the Buick Series C. Until GM assumed control of Chevrolet in 1917, the previous Model 42 and the Model 43 were GM's entry-level cars which led to the interrupted production of the Model 43 as Oldsmobile was promoted as a higher content product. It was also known as the "Oldsmobile Four" and competed with the Chevrolet Series H as an entry-level model until GM bought Chevrolet. It was the junior level product to the upscale Oldsmobile Light Eight. It was Oldsmobile's last four-cylinder car until 1977 with the Oldsmobile Starfire.
The Model M was a four-seat passenger car produced by Oldsmobile in 1908, offered as a mid-range alternative to the Model R Curved Dash runabout that appeared in 1901, replacing the Model A. It was the junior sedan to the first six-cylinder sedan called the Oldsmobile Model Z also introduced in 1908, but was larger than the Oldsmobile Model X.
The Model D was a four-seat passenger car produced by General Motors under the Oldsmobile brand in 1909, replacing the Model M. It was the last car engineered by Oldsmobile before it became a division of GM and began sharing a platform with Buick.

It continued to use the T-head engine for two years. The various bodystyles were supplied by Fisher Body of Detroit, MI. It competed with the Chevrolet Series C Classic Six as Chevrolet was an independent company before becoming a division in 1917. Oldsmobile also shared technology with GMC for commercial and industrial products.
The Oldsmobile Series 28, also known as the Autocrat, was a mid-level four seat passenger car produced by GM's Oldsmobile Division for 1911 and 1912. It was based on the top-level Oldsmobile Limited while using a four-cylinder engine, and was manufactured in Lansing, Michigan.
The Oldsmobile F-Series was a pre-WWII passenger car built from the 1928 through 1938 model years. The first generation continued the tradition of adding a series number for each model year; F-28, F-29, F-30 and F-31. The second generation, signified by a completely new bodystyle appearance was built from 1932 through 1938, all having been manufactured in Lansing, Michigan. 1926 saw the introduction of GM's most recognized business model, the use of common platforms shared amongst the brands, and Oldsmobile and Buick shared the GM B platform. The F-Series was shared with the Buick Master Six and was also known as the Oldsmobile Six which was introduced as a name earlier in 1913.
The Oldsmobile Light Eight was an automobile produced by the Oldsmobile Division of General Motors in roadster, two-door coupe, four-door sedan from between 1916 and 1923. It was powered by a sidevalve V8 engine, the maker's first, and shared with the 1916 Oakland Model 50.
The Oakland Six was the first six-cylinder engine offered by the Oakland Motor Company in 1913 which became a division of General Motors in 1909. The Oakland Six was offered in many different model names that changed every year, along with several body styles and engine displacements until 1929, when the V8 was reintroduced, then in 1931 Oakland was renamed Pontiac. When Oakland became a division of GM and introduced the Oakland Four, Oldsmobile and Buick shared bodywork and chassis of their six-cylinder models with Oakland. When Chevrolet became part of GM in 1917, Oakland chassis and bodywork were shared with Chevrolet. Manufacture of the Oakland was completed in Pontiac, Michigan.
The Pontiac 6 was a more affordable version of its predecessor Oakland Six that was introduced in 1926, sold through Oakland Dealerships. Pontiac was the first of General Motors companion make program where brands were introduced to fill in pricing gaps that had developed between Cadillac, Buick, Oldsmobile, Oakland and Chevrolet. The original marketing approach began when GM was incorporated in 1908 was to offer a range of vehicles in various body styles based on affordable to extravagant, and the customer base would gradually trade up every few years to the next hierarchy brand. Pontiac was introduced as an affordable Oakland, followed by LaSalle for Cadillac, Marquette for Buick and Viking for Oldsmobile. Pontiac's introduction was a sales success while customers shied away from the more expensive Oakland, and once the Wall Street Crash of 1929 and the Great Depression followed, both Pontiac and Oakland were being considered for cancellation but the decision was made to keep Pontiac as the economy began to recover.
