features standard power assist including front disc brakes with solid rotors, and rear drum brakes. Changes Following the introduction of the Skyhawk, in mid-1975, it was joined by a lower-priced and less well-equipped Skyhawk S. In 1976, a five-speed manual transmission became available as an option. Starting with the 1976 models, the front and rear disc rotors were of the vented type. Another new option was the Astroroof, which was a large, heavily tinted, overhead glass roof combined with a wide aluminum band that extended from one B-pillar across the roof to the opposite B-pillar. In 1977, a conventional sliding sunroof became optional and also could be ordered with the aluminum band. To commemorate the Bicentennial of the United States, the standard colors available on all Buicks were Judicial Black, Liberty White, Pewter Gray, Potomac Blue, Continental Blue, Concord Green, Constitution Green, Mount Vernon Cream, Buckskin Tan, Musket Brown, Boston Red and Independence Red, with specially available colors on select models Congressional Cream, Revere Red, Colonial Yellow and Firecracker Orange. For the 1979 model year, the Skyhawk received a facelift that incorporated single rectangular headlamps, replacing the previous dual rectangular headlamps that all models had used. A new option was the "Road Hawk" package that included a Rallye ride and handling package consisting of larger front and rear stabilizer bars, larger tires, and special interior and exterior trim. There was also a "Skyhawk Designers' Accent Edition" that was primarily an exterior trim package available in bright yellow or red with black trim. There were few changes for 1980, the last model year for the GM H-body platform, most notably the discontinuance of the five-speed manual transmission as an option and revisions to the interior decor. Only the four-speed manual and three-speed automatic transmissions were offered for 1980. The Skyhawk and Starfire failed to achieve the sales success of the Monza and Sunbird possibly because small sporty coupes seemed out-of-place in a Buick or Oldsmobile showroom. They were discontinued on December 21, 1979, to allow for more production of Monza and Sunbird hatchbacks. A total of 125,311 H-body Skyhawks were produced in six model years.
