This 1940 Buick Special Series 40 Convertible Coupe blends prewar elegance with postwar V8 performance thanks to a later-model drivetrain upgrade. While retaining its classic proportions and convertible charm, this example benefits from a 350ci Buick V8 and automatic transmission, making it far more usable and approachable for modern driving. The combination of vintage styling and mechanical updates gives this Buick a restomod character without straying too far from its original identity.
Exterior and Interior
Finished in a custom cream exterior, the car presents with smooth, flowing body lines and a custom paint job that complements its Art Deco–inspired design. A burgundy convertible soft top adds visual contrast and reinforces the period look. Inside, the cabin has been reupholstered in burgundy leather, with aftermarket seating, carpeting, and trim throughout. Additional aftermarket touches include updated dash instruments, a clock, and an AM/FM radio, though the radio is currently inoperative. Overall, the interior reflects a tasteful refresh rather than strict originality.
Engine
Power comes from a swapped-in 350ci Buick V8 from a 1968 Buick Skylark that is naturally aspirated and equipped with a 2-barrel carburetor, also paired to a 3-speed automatic transmission driving the rear wheels. This drivetrain conversion significantly improves drivability compared to the original straight-eight setup. An aftermarket lowered suspension gives the car a more planted stance while maintaining cruising comfort. The mechanical configuration prioritizes ease of use and reliability, making this Buick suitable for regular enjoyment rather than static display.
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.
