1937 Buick Special: Specs, Styles, Value, and History

The 1937 Buick Special occupies an important place in American automotive history. It was accessible within Buick’s range, yet it offered the presence, engineering, and comfort expected from a full-size automobile. For a broader point of reference, you can compare its design language with our 1935 classic car feature.

What makes this model especially interesting is the balance between production scale and surviving rarity. Buick built the Special in substantial numbers for 1937, but many examples have since disappeared, been modified, or lost their original bodywork. A period-focused account from Hemmings’ 1937 account identifies the model’s expanded body range, new styling, and larger straight-eight engine as defining changes.

What was the 1937 Buick Special?

The 1937 Buick Special was the Series 40, Buick’s entry-level full-size model for that model year. The name had replaced the earlier numerical naming system in 1936, when Buick reorganized its range around names such as Special, Super, Century, Roadmaster, and Limited.

That positioning matters. The Special was not Buick’s most expensive or prestigious car, but it was not a small economy vehicle either. It gave buyers a substantial American automobile with a long chassis, a smooth eight-cylinder engine, and a wide choice of closed and open body styles.

Its role also explains why the model became a volume leader. Buyers could obtain Buick styling and mechanical character without moving into the higher-priced parts of the range. This created a car with strong historical importance, even though collectors sometimes focus more attention on senior Buicks and dramatic convertibles.

The 1937 model year also arrived during a period of rapid styling development. Automakers were moving toward integrated fenders, wider grilles, improved cabin sealing, and more unified body design. The Buick Special reflects that transition clearly, making it useful for understanding how American cars moved from separate prewar forms toward more modern shapes.

Which specifications define the 1937 model?

The central mechanical feature was Buick’s 248-cubic-inch overhead-valve straight-eight. It produced a rated 100 horsepower and was paired with a three-speed synchromesh manual transmission. The car used front-engine, rear-wheel-drive architecture, which was conventional for a full-size American car of the period.

For 1937, the wheelbase increased to 122 inches. That longer platform gave the Special a more imposing stance and helped provide room for five-passenger sedan configurations. The average vehicle weight was approximately 3,488 pounds, while period testing recorded a 10-to-60-mph time of 19.2 seconds, according to the previously cited Hemmings account.

These figures should be interpreted in their historical context. The straight-eight was designed for smoothness, relaxed cruising, and strong low-speed response, not modern acceleration. Its long engine layout and steady power delivery are part of the driving experience collectors seek today.

The 1937 Buick Special also introduced practical engineering refinements. The chassis used front and rear stabilizer bars, while revised generators and hypoid gears supported improved road manners. These details do not make the car a sports machine, but they helped distinguish the new model from earlier Buicks.

Today, the mechanical specification is valuable because it establishes an authenticity baseline. A collector evaluating an example should determine whether the engine, transmission, axle, instruments, and major chassis components correspond with the correct model year. A modified car can still be enjoyable, but originality affects historical interpretation and market positioning.

Which body styles were available?

Body style is one of the most important variables when comparing 1937 Buick Special cars. The range included business coupes, sport coupes, two-door sedans, four-door sedans, and open configurations. Some versions carried trunks, while others used a more formal plain-back design.

A detailed appraisal guide lists several 1937 Series 40 variants, including the Model 46 business coupe, Model 46-S sport coupe, Model 44 two-door sedan, Model 48 two-door sedan with trunk, Model 47 four-door sedan, and Model 41 four-door sedan with trunk.

The production figures in that guide show how differently these versions were distributed. The four-door sedan with trunk is listed at 82,440 units for 1937, while the business coupe is listed at 13,742. The sport coupe is listed at 5,059, which helps explain why certain body styles attract more attention from collectors.

Open cars occupy a different place in the market. The convertible phaeton offered a more dramatic ownership experience, but its exposed cabin, folding top, and specialized trim create additional restoration challenges. A sedan may be easier to use and maintain, while a convertible can deliver greater visual impact when correctly restored.

When assessing a body style, you should look beyond rarity alone. A scarce model with incorrect replacement panels may be less valuable than a more common sedan with strong documentation, original trim, sound structure, and a sympathetic restoration.

How did the 1937 Buick Special look?

The 1937 design introduced a more integrated appearance. The grille, hood, front fenders, and headlamps were redesigned, while the body adopted all-steel construction. The result was a cleaner and more unified silhouette than the upright forms associated with earlier Buick models.

The grille remained a dominant visual element, but the surrounding sheet metal gave the car greater width and presence. The fenders were more closely integrated with the body, and the headlights contributed to a more modern front-end treatment.

Inside, the dashboard also received attention. The cabin was still formal by modern standards, but the instruments and controls were arranged within a more cohesive design. Wood, painted metal, glass, and upholstery combined to create the period’s distinctive sense of occasion.

If you are comparing design developments across the decade, our 1936 Chrysler feature provides a useful neighboring reference. The comparison shows how manufacturers were pursuing similar goals while retaining different proportions, grille treatments, and brand identities.

The Buick Special’s appeal comes from this combination of restraint and scale. It is not as visually extreme as some later prewar customs, but it has enough chrome, length, and formal detailing to read immediately as a substantial 1930s American automobile.

How does it fit into 1930s American car history?

The 1937 Buick Special helps explain the structure of the American automotive market before the Second World War. Manufacturers offered several overlapping ranges, allowing buyers to move upward through styling, equipment, engine size, and price.

Buick placed the Special below its larger and more expensive lines, yet the car still benefited from the company’s engineering reputation. It demonstrates how a manufacturer could use a shared corporate design direction while giving each series a distinct position.

For wider historical context, our 1930s American cars guide places the Special alongside the period’s broader design trends. Those trends included longer bodies, integrated fenders, improved cabin comfort, larger glass areas, and increasing attention to aerodynamic appearance.

The model also reflects a changing relationship between utility and luxury. A four-door sedan could serve as practical family transportation, while the same mechanical foundation supported coupes and open cars with a more expressive character.

That versatility is one reason the Series 40 remains relevant to collectors. It was not built for only one narrow audience. It served everyday buyers, professional users, and customers who wanted a more stylish automobile without moving to Buick’s highest-priced offerings.

What is a 1937 Buick Special worth in 2026?

There is no single 2026 price for a 1937 Buick Special. Condition, body style, originality, restoration quality, provenance, and location can move the value substantially in either direction.

An online valuation page updated in August 2026 reports an estimated range of $15,295 to $34,495, with a median value of $22,995 and an average of $32,322. The figures come from the site’s stated sample of recent market data, so they should be treated as an indication rather than a universal appraisal. You can review the August 2026 valuation for the methodology and condition descriptions.

The lower end generally corresponds with cars requiring cosmetic, trim, or mechanical work. A solid driver with documented maintenance can sit closer to the middle of the range. A highly finished example with correct details, strong provenance, and professional restoration can move toward the upper end.

Body style also influences buyer interest. Convertibles, phaetons, and distinctive coupes often attract greater attention, but they can require more specialized restoration work. Four-door sedans may offer a lower entry point and greater practicality, especially when the body and interior are complete.

In 2026, buyers should also account for the difference between asking prices and completed sales. A high advertised price does not prove that a vehicle achieved that value. The strongest evidence comes from documented transactions involving cars with comparable condition, configuration, originality, and history.

What should you inspect before buying one?

A careful inspection should begin with the body and chassis. Look for rust around the lower doors, rocker areas, fenders, floor sections, trunk, and windshield surrounds. Repairs hidden beneath thick filler can be expensive to correct, particularly when the car has already received an older restoration.

Next, inspect the straight-eight engine. Cold-start behavior, oil pressure, smoke, overheating, unusual valve noise, and evidence of coolant contamination can reveal problems that are not visible in photographs. A compression test and cooling-system inspection are sensible steps before purchase.

The transmission, clutch, brakes, steering, and suspension also deserve attention. These systems may function adequately during a short drive while still requiring substantial work. A specialist familiar with prewar American cars can identify worn components that a general inspection might overlook.

Documentation is equally important. Ask for restoration invoices, engine numbers, ownership history, period photographs, and records showing when major work was completed. If the car is presented as original, verify that claim against its body style, trim, mechanical components, and known production details.

Finally, decide what type of ownership you want. A concours restoration demands different priorities from a usable touring car. The best purchase is usually the example that matches your intended use, budget, mechanical resources, and tolerance for future restoration work.

Why does the 1937 Buick Special still matter?

The 1937 Buick Special matters because it combines historical scale with recognizable engineering character. It represents a moment when American manufacturers were refining the full-size automobile without abandoning the formal presence that buyers expected.

It also offers several legitimate collecting paths. You can pursue a rare open body, a carefully preserved sedan, a period-correct driver, or a restored example intended for display. Each path rewards different qualities, and none should be judged only by headline price.

For collectors building a broader design narrative, our classic cars archive can help place the Buick within a wider conversation about mechanical identity, visual culture, craftsmanship, and automotive history.

The most compelling examples are not necessarily the newest restorations. They are the cars with coherent specifications, honest condition, clear history, and a character that remains faithful to the period. That combination gives the 1937 Buick Special lasting relevance beyond simple nostalgia.
