2023 Muscle Car Market Review - Buick Performance 1963-1980
Australia saw plenty of 1960s Rivieras imported as new cars but not many of Buick’s more overt muscle cars; the GS400/455s and Wildcat. All except the Skylark-based GS were considered by Buick as ‘full-sized’ cars and had engines of at least 400 cubic inches (6.6 litres).
With few in our sample, the GS average was skewed by inclusion of a $130,000 GS455, however excellent examples of the GS400 should cost around $60,000. First-series, 1963-65 Rivieras were hard to find, however plenty of the stylish 1966-70 cars remain available and $50,000 was typical for one in excellent condition.
Only one Boat-Tail (1971-74 Riviera) appeared during our survey and at less money than usual for the model.
