The Chevrolet National (1928), International (1929), and Universal (1930) were Chevrolet's direct competitors to the Ford Model A. They represented a significant advancement for the brand, most notably with the 1929 introduction of the overhead-valve inline-6 engine. Marketed as "A Six for the price of a Four," this new engine, known as the "Stovebolt Six," gave Chevrolet a major performance and refinement advantage over Ford's 4-cylinder cars.
Collectors appreciate these models for their historical role in establishing Chevrolet as a true rival to Ford. The durability of the Stovebolt Six and the wide array of available body styles, from affordable sedans to sporty roadsters, make them appealing. They offer a genuine pre-war driving experience and benefit from strong club support and parts availability, making them relatively easy to own and maintain.
The market for these late-20s Chevrolets is broad. An average price of around $12,839 indicates that nice, driver-quality cars are accessible to many collectors. However, the range is wide, with project cars trading for just a few hundred dollars while pristine, restored examples of rare body styles can exceed $35,000.
Buying Tips
- Inspect the wood body framing carefully for rot, especially in the sills, door posts, and floor supports. Steel panels are just a skin on many bodies.
- The "Stovebolt Six" engine is tough, but check for cracks in the block and listen for bearing noise. Ensure it runs smoothly without excessive smoke.
- Authenticity is key to value. Check that the engine, chassis, and body numbers align and that major components are period-correct.
- Prices vary greatly by body style. Sedans are the most common and affordable, while open cars like roadsters and phaetons command a significant premium.
Prices range from $350 for project cars to $35,760 for expertly restored examples.
