This is a Special Edition 1979 Buick Skyhawk called a ROAD HAWK. Essentially it is a silver Skyhawk with the 'Y43' Road Hawk option package which included special front air dam, rear spoiler, quarter panel extensions, dark grey paint and red pinstriping with hawk and 'ROAD HAWK' decals and, of course, the special Road Hawk seats. This option was only avaiable on 1979 and 1980 Buick Skyhawk's.
I won the car on ebay in November, 2003, flew to Phoenix, Arizona to buy and pick it up and drove it home to Toronto, Ontario, Canada. It needs new paint, decals and pin striping but all the Road Hawk special features are present (the front air dam is busted but being reproduced). It requires some work, but a rust-free, mostly complete car is a good start.
