6. 1969 Pontiac GTO Judge Ram Air IV Convertible (10 Made)
Pontiac’s GTO Judge Ram Air IV convertible reigns as one of the most coveted open-air thoroughbreds. Powered by a 400-cubic-inch Ram Air IV V8 featuring high-flow aluminum heads and an 800-cfm four-barrel carburetor, it delivered a healthy 370 horsepower and 445 lb-ft of torque.
With a four-speed manual, the Judge convertible erupted from 0-60 mph in about six seconds and covered the quarter mile in the low 13s. Sporting its trademark “The Judge” graphics, three-speed Hurst shifter, and high-rise dual exhaust manifolds, only ten Ram Air IV convertibles rolled off the line—making each an open-top missile revered by collectors.
