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.

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.
