The Buick Limited was an automobile built by Buick between 1936 and 1942 and during model year 1958. Since 1959 Buick has used the "Limited" name to denote those models which featured a high level of trim and standard options in its various model ranges.
The Series 90 had an 344.8 cu in (5,650 cc) in-line eight-cylinder engine, developing 104 bhp of power at 2,800 rpm. Also due to its size, it was the top model of the Buick range, using the GM "C-body" platform shared with Cadillac. The next year the pace grew and was introduced a new high performance engine power unit developing 113 hp. In 1933 the model was completely revised. In 1931, however, the running board was shortened and the engine output increased again, reaching 116 hp. The appearance was updated, while the mechanics remained unchanged, and Buick manufactured 43,321. In 1936 the model changed its name to "90 Limited".
The origins of the Limited name date to 1936 when Buick added names to its entire model lineup to celebrate the engineering improvements and design advancements over their 1935 models. It shared its chassis with the top-level Cadillac D body vehicles. Buick had released a new line of cars that were technically superior to their predecessors by offering such features as all-steel passenger compartment tops (GM's Turret Top design), improved front suspension, improved hydraulic safety braking system, alloy engine pistons and an improved engine cooling system. Buick's Series 40 was named the Special, the Series 50 became the Super, the Series 60 was named the Century, the Series 80 was named the Roadmaster, and the Series 90 — Buick's largest and most luxurious vehicle — was named the Limited. The engine was a 320 cu in (5,243.9 cc) 120 hp (89 kW) I8
Limiteds were the most expensive Buicks in production, riding on the company's longest wheelbase of 138 in (3,505 mm), and the best appointed cars that Buick built. All Limiteds were built at the Buick factory in Flint, Michigan, while all Cadillacs were built in Detroit at the Clark Street Facility. The name Limited was truly appropriate to the cars themselves which were limited to touring sedans and limousines; its sales too were the smallest of Buick's entire model range:
