For 1954, Buick completely redesigned the Roadmaster and shared its new C-Body platform with the Super Line. In 1957, it was given a new body, 10 extra inches to its length, and a rakishly lower roofline. The Series 70 Roadmaster came in two- and four-door hardtop and convertible models. It was given sweepspear side accents, front-fender 'ventiports,' 'Dagmar' bumpers and fully-radiused rear fenders. Inside, there was a padded dashboard, several options of premium upholstery choices and a bright metallic overall dash motif. The 76C Convertible Coupe models were even more luxurious, with rich leather upholstery.

Benefitting from their involvement in NASCAR competition, Buick introduced the 322 cubic-inch 'Nailhead' v-8 in 1953. This evolved into a 364 cubic-inch, 300 bhp powerplant for 1957. This engine was shared with the Century line and featured a 10.0:1 compression ratio, and fitted with either a Carter or a Rochester four-barrel carburetor.

For 1957, there were just 4,364 examples of the Roadmaster Convertible produced, and each carried a base price of $4,066. This example has been given a nut-and-bolt, body-off restoration and finished in two-tone black and red. It has a black Everflex top with a red top boot, a red leather interior and 40-spoke chrome wire wheels with whitewall tires. There are power brakes, power steering, power windows, Wonder Bar pushbutton AM radio and power antenna, a heater/defroster and a clock.

In 2011, the car was offered for sale at the RM Auction in Scottsdale, Arizona. It was estimated to sell for $125,000 - $150,000. As bidding came to a close, the car had been sold for the sum of $121,000 including buyer's premium.
