The 1960s marked a return to form for Alfa Romeo. After years of stagnant offerings, cars like the SZ, TZ, and TZ2 mad the Italian company a force in racing in Europe and the US. Introduced in 1962, the Giulia brought Alfa success in the production racing classes, especially with the Sprint GT, which formed the basis for the wildly successful — and beautiful — GTA. This 1966 Giulia GTA has some serious racing history behind it, winning the inaugural SCCA Trans American Sedan Championship in 1966 — the series that would become known as Trans-Am and spawn Pontiac's famous Firebird model. After being sold in 1967, this GTA would continue to be raced in period and historic events through the present day. In flawless condition and one of the most famous racing GTAs around, this sought-after car isn't going to be on the showroom floor for long.
