Introduced in 1925, the Buick Standard Six and Master Six established a two-model strategy that served the brand well. The Master Six used a longer wheelbase and a larger engine, positioning it as the premium offering, while the Standard Six provided Buick's famed "Valve-in-Head" overhead-valve performance to a wider audience. These cars were known for their reliability and power, helping Buick solidify its place as a top American automaker in the late 1920s.
Collectors are drawn to the Standard and Master Six for their pre-war engineering and diverse range of body styles. From sporty roadsters to stately sedans, there's a model for most tastes. The overhead-valve six-cylinder engine was a signature Buick feature that offered a performance advantage over many contemporary flathead engines. They represent an accessible entry point into collecting cars from the Roaring Twenties.
The market for these Buicks is modest but steady, with an average sale price around $25,000. The wide price range reflects condition and body style, with open cars like tourers and roadsters commanding significant premiums over more common sedans. Restored, show-quality examples fetch the highest prices, while unrestored project cars can still be found at the lower end of the market.
Buying Tips
- These cars use a wooden internal frame, so check for wood rot by looking for sagging doors and uneven body panel gaps.
- The OHV six-cylinder engine is robust, but listen for excessive valve train noise and check for oil leaks, especially from the rear main seal.
- Early models have two-wheel mechanical brakes, which are marginal in modern traffic. 1929 and later models featured safer four-wheel brakes.
- Verify the vacuum fuel tank system is operational. Many have been converted to electric fuel pumps, which affects originality.
Prices range from $4,230 for project cars to $60,000 for restored, open-body variants.
