Few automobiles occupy a more fascinating corner of Corvette history than the five original 1963 Chevrolet Corvette Grand Sports.

They weren't production Corvettes with bigger engines. They weren't ordinary Sting Rays converted into race cars. And despite their familiar C2 silhouette, they shared surprisingly little with the Corvette sitting on a Chevrolet showroom floor in 1963.

With each passing decade, new generations enter the classic car world looking for fun and affordable project cars. In the '80s, the second-gen Camaro and Firebird were common entry-level choices, and in the '90s and early '00s, the third-gen IROC-Z and Trans Am filled the same role. Today, clean examples of all of those cars have become more scarce and therefore more costly. Fourth-gen GM F-body cars like this 1999 Trans Am WS6 offer huge restomod and performance potential without breaking the bank.
