As opposed to supercars and expensive custom-built dream machines, classic muscle cars were always designed with the average consumer in mind. They were mass-produced to be cheap, powerful, and impressive to look at. Thanks to varying trim levels and engines, however, a large number of muscle cars had runs of fewer than 100 units. Today, these cars are highly sought-after collectibles that sell for far more than they originally cost.
Perhaps the rarest muscle car ever to roll off an assembly line is the 1967 Dodge Coronet R/T 426 Hemi convertible. Only 238 units were produced, and of those, just two were convertible specimens – one each in manual transmission and automatic. Like many of the rarest muscle cars, it used the powerful 426 Hemi engine, which produced an astonishing 425 brake horsepower (BHP).
The 1970 Plymouth Road Runner 426 Hemi features the same engine as the 1967 Dodge described above, and again, it is the convertible model that turned out to be exceptionally rare. Only three were ever produced. Leather seats and special hydraulic lifters distinguish this rare vehicle.
One of the flashiest muscle cars ever produced, the 1970 Dodge Super Bee Fastback came in an array of ill-advised colors, including royal purple and pink. The version of the Super Bee with a 426 Hemi engine was barely ever ordered, so only four 1970 Super Bee 426 Hemi Fastbacks were made that year.
The muscle car was the great American equalizer – a mean, fast driving machine that wouldn’t break the bank, and sacrificed luxury for power. The fact that so many muscle cars ended up being so rare is an odd and interesting twist in their history.
