1929 Buick Seven Passenger Four Door Sedan

Here is a 1929 Buick Series 129 Sedan that really gives you good glimpse of a luxury car prior to the 1930’s. The year 1929 was special for Buick as it was the marquees Silver Anniversary. Not only was the first Buick for sale manufactured in 1904 but the marquee is considered the oldest American car brand still in production today. After all the car brands discontinued over the decades, this is significant.

The Buick 129 Series

In 1929 there were three series of cars offered by Buick. These were the 116, 121 and 129 Series. Each one of these series reflected the wheelbase length. The 129 Series, which includes the featured automobile in this article, came in a variety of models. These included the Sedan, Convertible Coupe, Standard Coupe, Phaeton, Limousine, both five and seven passenger Sedans and Touring models.

1929 Buick Styling

Buick was positioned by General Motors to be a luxury car ranked under the Cadillac and above the Pontiac. Chevrolet the the lowest and least costly brand.

The style of the 1929 Buick is a story in itself and takes us back to the early days of Harley Earl, one of the most well known of the twentieth century auto designers. Essentially, it was a difference of opinion between Earl and the Fisher Body people. Harley Earl designed a Buick which in 1929 meant mostly a lot of straight lines.

When Fisher Body got a hold of the design they made a few alterations that resulted in a slight bulge just below the middle. The car was thus referred to as the “pregnant Buick” although noticing this difference from Earl’s design was not easily seen by the average observer.

The end result of this dust up was that Harley Earl obtained the support of Alfred Sloan, GM President, and in the future Earl’s design team would be consulted of any design changes prior to them being implemented. This was a big victory for Earl and helped his career quite a bit.

Many collectors know that Harley Earl has been called the father of the Chevrolet Corvette. From the 1920’s Buick to the introduction of the Corvette and beyond gives you a good idea of Earl’s career.
