Snake in the Grass: 1967 Shelby GT500 Super Snake
A true one-of-one Mustang, the 1967 Shelby GT500 Super Snake was built as a high-speed tire test vehicle for Goodyear. Equipped with a 427ci V8 from the Ford GT40, this car had a top speed exceeding 150 mph. Its rarity makes it one of the most valuable Mustangs ever.
