Shelby GT350 R
Produced only in 1965 and sold to privateers and racing teams all over America and the world, Shelby GT 350 R was a pure racing beast. Those cars were not street-legal and were used purely for racing purposes, something that they did exceptionally well (via Supercars).

The same 289 V8 powered the R version as the regular Shelby GT350, but it had close to 400 HP and numerous racing modifications. The car was light and well-balanced, and it proved extremely fast, winning races in America, Europe, and South America as well. Shelby made only 34 so you’ll need the fortune to own one today. All cars were 1965 model year.
