Overview of 1937 Buick Special Series 40 Convertible Restomod Supercharged For Sale by Owner

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.

SOLD

This 1940 Buick Special Series 40 Convertible Coupe blends prewar elegance with postwar V8 performance thanks to a later-model drivetrain upgrade.

The combination of vintage styling and mechanical updates gives this Buick a restomod character without straying too far from its original identity.

The 1999 Buick Riviera Silver Arrow Limited Edition marked the end of an era, serving as a commemorative send-off for the Riviera nameplate after decades as one of Buick’s most distinctive personal luxury coupes. This example is #27 of just 200 produced and shows only 28,978 miles. Finished in Sterling Silver Metallic over a Medium Gray leather interior, it pairs understated late-1990s luxury with the stronger personality of Buick’s supercharged 3800 Series II V6. Special Silver Arrow badging, interior logos, and its numbered plaque distinguish this car from a standard Riviera, while the low production count gives it genuine collector appeal.

The 1966 Plymouth Belvedere II Hardtop is the kind of Mopar that gets enthusiasts interested before the hood is even opened. Its clean B-body lines, pillarless hardtop profile, Soft Yellow paint, black vinyl roof, and Magnum 500-style wheels give it the restrained factory muscle look of the mid-1960s, but this example carries much more serious hardware underneath. Showing approximately 91,610 miles, it is powered by a 440ci big-block V8 backed by a TorqueFlite 727 automatic, giving it the kind of drivetrain combination that feels right at home in a classic Plymouth. Add power steering, power disc brakes, air conditioning, and a dual exhaust system, and this Belvedere blends old-school Mopar attitude with enough comfort to make it more than just a weekend bruiser.
