The Green Boattail

"In 1971, Buick produced one of the most controversial cars it has offered in modern times; a restyled Riviera with a rear end that swept down to a point, or "nostril", as one disigner put it. Not since the Thirties had a major manufacturer offered a style that could be called a boattail. This one could."

"A sensational new Riviera debuted for 1971. A large car with a boattailed rear roof and window section and sweeping side sculpture greeted 1971's Riviera customers. Wheelhouses were wide open after a year of skirted fenders. Riviera shared Full-Flo ventilation with other Buicks and had the louvers on the deck lid. Standard features were numerous and included heater and defroster; Custom padded contoured seats; deep pile carpeting; electric clock; smoking set; head restraints; new seat belt system; inside hood lock release; variable power steering; TurboHydramatic; power front disk brakes and dual exhausts."
