1957 Buick Series 75 Roadmaster Convertible Coupe / 7D4011713 Chassis Information

1957 Buick Series 75 Roadmaster
Convertible Coupe
Chassis #: 7D4011713
Sold for $88,000 at 2010 Gooding and Company - Pebble Beach Auctions.
Sold for $61,600 at 2012 Gooding and Company - The Scottsdale Auction.
This Buick Roadmaster Convertible (of which there were fewer than 4,500 produced) is finished in two-tone Seminole Red and Dove White. It was the subject of a body-off restoration and rewarded with a First National Award at the Louisville AACA Meet and Best of Show at the Hawkeye Buick Show. The interior is upholstered in red leather and the panoramic windscreen, exquisitely trimmed dashboard and delightful 1950s design features combine to create a beautiful interior space.

The Roadmaster was equipped with many standard features, most of which were extra-cost options on other Buick models. It has optional power steering, Sonomatic radio, wheel covers, deluxe steering wheel and factory air-conditioning.

Power is from a 364 cubic-inch overhead valve 'Nailhead' V8 engine with a single 4-barrel carburetor. It produces 300 horsepower and is mated to a Dynaflow automatic transmission. There are four-wheel hydraulic drum brakes and an independent front suspension.

In 2012, the car was offered for sale by Gooding & Company at their Scottsdale, Az. auction. The car was estimated to sell for $110,000 - $140,000 and offered without reserve. The car found new ownership for the sum of $61,600, inclusive of buyer's premium.
