About the Buick Roadmaster
The 1938 Buick Roadmaster represented a significant leap in refinement for the brand, introducing the 'Dynaflash' overhead-valve straight-eight engine and coil-spring rear suspension. Built on the longer 133-inch wheelbase, it offered a level of prestige and ride quality that rivalled Cadillac at a more accessible price point. The 1938 model is particularly noted for its updated styling, featuring a more prominent grille and integrated headlights. It remains a highly sought-after pre-war classic for its robust mechanicals and effortless touring capabilities.

Buick Roadmaster fun facts
- The 1938 Roadmaster was one of the first mass-produced cars to feature rear coil springs, replacing the traditional leaf spring setup for a much smoother ride.
- The 5.2-litre engine used 'turbulator' pistons, which increased the compression ratio to 6.5:1, a high figure for the era.
- The 1938 model year saw the introduction of the 'Self-Shift' semi-automatic transmission as an option, though most Roadmasters retained the floor-mounted manual.
