1940 Buick Series 70 news, pictures, specifications, and information
Touring Sedan
Chassis Num: 12751447
Engine Num: 73862989
Sold for $36,300 at 2007 RM Auctions.
1940 was a big year for the Buick marque, with registration passing the 233,000 mark, which was something it had not done since 1926. Buick introduced the Estate wagon and the Super line in 1940, adding to pedigree of the Buick marque.

The Buick vehicles became more modern in design in 1940 by phasing out such design cues as the side-mounted spare tires and the running boards.

This 1940 Buick Roadmaster Sedan Model 71 was offered for sale at the 2007 RM Auctions held at Meadow Brook. It was offered without reserve and estimated to sell between $25,000 - $35,000. It is powered by a 320 cubic-inch eight-cylinder engine capable of producing over 140 horsepower. There is a column-mounted three-speed sliding gearbox and four-wheel hydraulic drum brakes. It is finished in black with a gray and white pinstriped interior. It has been treated to a full body-off-the-frame restoration to concours quality in 1988. It has earned its AACA National badge and an AACA Senior National win.

Though it has an older restoration, it is still in good condition. At auction, the high bid exceeded the estimated value; the car was sold for $36,300 including buyers premium.

Touring Sedan
This 1940 Buick Series 70 Roadmaster Convertible Sedan is one of the last four door convertibles made by Buick, and has an interesting history. Purchased from the owner of Sailorman in Ft. Lauderdale, it was then sent to a restoration shop in Melbourne, Florida. While there it was fitted with new red leather interior, tan cloth top with red piping, and a complete paint job on a very clear body. The wide whites compliment the look and the ride, and this three speed, 320 cubic-inch OHV eight Buick performs as it should. Lea Francis Ltd of W. Palm Beach went through the mechanicals, and they fitted it with a new fuel pump just prior to its trip North. Only 235 of these Roadmaster Phaetons were produced, and it unknown how many exist in modern times.

As the 1930s came to a close, Buick adopted an all eight-cylinder range that would continue through to World War II and beyond. The 1940 Roadmaster was designated the Series 70 and was positioned just below the top-of-the-range Limited Series 80, in the model line-up. It shared its styling with the Super and was available as a Touring Sedan, Convertible Phaeton, Convertible Coupe or Sport Coupe. The 76C Convertible Coupe sold for $1,430 and just 6060 examples were built. This was the last time Buick offered sidemounts and the first time 'Fore-N-Aft' directional indicators were added, an industry first.

This Roadmaster Convertible Coupe was once owned by automotive adventurer Martin Swig who purchased the car in 2006. At the time of purchase, it wore an older restoration but was still a driver-quality vehicle. A short time later, swig sold the car to a close friend. The car was then prepared for the month-long, 7,600 Peking-to-Paris Motor Challenge. After its return to the US, the Buick was comprehensively gone through as needed. It has since participated in the California Mille on two occasions.

In 2012, this car was offered for sale at the Quail Lodge Sale presented by Bonhams. The car was estimated to sell for $50,000 - $60,000. As bidding came to a close, the car had failed to find a buyer willing to satisfy its reserve. It would leave the auction unsold.

The Roadmaster named first appeared on Buick automobiles in 1936 as a celebration of their engineering improvements and advancements in design. The Buick Series 80 became known as the Roadmaster. The Roadmasters were built on the longest wheelbase Buick had to offer. From 1946 through 1957 they were the most elegant and prestigious automobiles that Buick sold.

From 1936 through 1948 the Roadmaster appeared in coupe, sedan, convertible and station wagon bodystyles. A hardtop coupe was added in 1949 and dubbed the Riviera.

The Roadmaster named reappeared in 1991 and continued in production until 1996. It served as a replacement for the Electra model line and offered as an Estate Wagon. A sedan was introduced in 1992.

The end of the 1953 Buick Roadmaster station wagon meant the end of the last wood-bodied station wagon to be mass-produced in the United States. In 1996, the end of the Buick Roadmaster Estate Wagon meant the end of the full-size family station wagons.
