Introduced in the middle of the 1955 model year the four-door Buick Special Riviera (along with the Century Riviera, the Oldsmobile 98 Holiday, and the 88 Holiday) were the first four-door pillarless hardtops ever produced. By then, the Buick Special was one of America's best selling automotive series. For 1956 the larger 322 cu in V8 engine was shared with the rest of the range, although it was replaced by the bigger, 250 hp 364 V8 for 1957. This year also brought all-new bodywork, as well as a four-door hardtop station wagon called the Buick Caballero. The 1957 wheelbase remained 122 inches. In the June, 1957 issue of Popular Mechanics, the Special was rated with a 0-60 mph time of 11.6 seconds and fuel economy of 17.4 mpg-US at 50 mph.This particular '57 Buick Special Riviera two door hardtop is an amazing custom work of art that has had tens of thousands of dollars invested to make it what you see today. This is a two time World of Wheels competitor that comes with Air Ride suspension, 4-wheel disc brakes, custom leather interior, A/C, custom front grill, shaved door handles, decked trunk and louvered and shaved hood and a host of custom touches to make this Buick truly one of a kind. Finished in purple, the paint on the car is in wonderful condition and was applied to a very straight body. The rear end had custom, 1959 Cadillac tail lights installed in the original Buick surrounds which looks great. Both bumpers have been rechromed and look great. The front bumper houses twin spotlights. The same goes for the trim and stainless bright work. The steel hood has been louvered which looks great and shaved of its emblems.
