Summary:
During the golden era of American muscle cars, many models were mass-produced, but those equipped with high-performance engines like Hemis, Cobra Jets, and Ram Air IVs were always rare and expensive. Over time, these already limited models became even scarcer. Some muscle cars were produced in such small numbers due to special orders, prototypes, or low consumer interest, making them extremely rare today.
This list highlights 10 of the rarest American muscle cars ever made, each with a known production count of nine or fewer. These include:
- 1969 Pontiac Firebird Trans Am Convertible: Only 8 produced, featuring a 400-ci Ram Air III V8.
- 1969 Pontiac GTO Judge Ram Air IV Convertible: Just 5 with manual transmission and Ram Air IV engine.
- 1966 Shelby GT350 Convertible: Only 4 built for testing, never intended for public sale.
- 1970 Plymouth Roadrunner Hemi Convertible: Just 4 equipped with the legendary 426 Hemi.
- 1969 Hurst/Olds Convertible: 3 promotional cars made, never publicly sold.
- 1966 Shelby Cobra Super Snake: Only 2 built, one destroyed in an accident; the other sold for $5.5 million.
- 1969 Chevrolet Corvette ZL-1: Just 2 produced due to high cost of the aluminum L88 engine.
- 1970 Dodge Coronet R/T Hemi Convertible: Only 2 with 426 Hemi and convertible option.
- 1967 Shelby GT500 Super Snake: Only 1 built, used for tire testing; later sold for $3.85 million.
