9. Buick Regal Sport Coupe (Turbo)
The Buick Regal Sport Coupe Turbo signaled a new era for American performance cars in the early ’80s. Its turbocharged V6 engine was a bold move, laying the groundwork for the legendary Grand National and GNX models that followed.
While the later GNX stole the spotlight, the earlier turbo Regals offered impressive acceleration and a unique blend of luxury and muscle.
Today, these models are often overlooked, but their role in Buick’s turbocharged legacy is undeniable. Details at Hemmings.
