1970 Buick GSX 2 Door Hardtop
The Buick Skylark was the first model to bear the Gran Sport badge in 1965, but the GSX appeared in 1970 with a big-block V8, a Ram-Air hood and a sport suspension. Only 678 units of the GSX were built that year, of which 500 were painted Saturn Yellow and 178 were painted Apollo White. Powered by a 350-hp, 7.5-litre V8.
