18. 1972 Buick Skylark GS
The 1972 Buick Skylark GS delivers impressive muscle and elegant styling, yet it’s long been overshadowed by more famous GM siblings. Collectors are beginning to appreciate its potent V8 and refined features, leading to a quick rise in value. Well-maintained examples are now commanding $28,000 or more at auction. The Skylark GS’s combination of power, comfort, and understated appeal is finally earning the recognition—and prices—it deserves.
