The 1937 Buick Special Series 40 Convertible represents a distinctive moment in prewar American automotive design, blending elegant Art Deco styling with the smooth, streamlined proportions that defined Buick’s entry-level luxury models of the era. While Buick was known for refinement and engineering sophistication in the 1930s, this example advances that legacy by integrating modern performance and comfort into a classic platform. Finished in Silver and fitted with a Carson-style removable top, this restomod preserves the graceful lines of the original convertible while transforming it into a high-performance cruiser that bridges prewar aesthetics and contemporary hot rod culture.
Exterior and Interior
The exterior of this 1937 Buick Special Series 40 Convertible features a custom Corvette-style silver finish that highlights the flowing fenders, long hood, and low stance characteristic of the Series 40, while polished brightwork and aftermarket wheels add a restrained modern contrast. The Carson-style removable top maintains a period-correct convertible appearance while enhancing usability. Inside, the black interior is cleanly executed with custom upholstery, a modern gauge cluster integrated into a simplified dashboard, and an aftermarket sound system discreetly incorporated to retain a vintage visual character while offering contemporary functionality.
Engine
Power is supplied by a 427ci tall-deck supercharged V8 equipped with a BDS Roots-style supercharger and dual four-barrel carburetors, providing performance far beyond the vehicle’s original specifications. Power is delivered through a TH400 three-speed automatic transmission to a rear end with a 3.73 gear ratio, offering a balance between strong acceleration and highway drivability. A custom chassis supports the drivetrain, complemented by four-wheel disc brakes and air conditioning, resulting in a mechanically robust build designed for confident modern road manners while accommodating the engine’s substantial output.
Inspection
This 1957 Buick Roadmaster Riviera 2-Door Hardtop is pure late-1950s American excess in the best possible way, combining dramatic Harley Earl-era styling with the torque-rich character of Buick’s Nailhead V8. Showing approximately 14,574 miles, this example was refurbished in the late 2000s and is finished in Dover White and Bittersweet Red over a Rust and Ivory interior. The car was later upgraded with an Air Lift Performance air suspension system. Add in power steering, power brakes, power windows, a power front bench seat, Hot Rod Air climate control, and wide whitewalls, and this Roadmaster delivers the extravagant look of a flagship ’50s Buick with a few thoughtful upgrades that make it even more enjoyable today.
