Plymouth Rapid Transit muscle car concepts bring six figures each

A little over a month ago,

we told you about a group of factory-customized Plymouth muscle cars that were used on the Plymouth Rapid Transit show circuit

. It was a promotional tour that demonstrated how you could potentially customize a then-new

Plymouth

. The cars were amazing period pieces that looked like classic Hot Wheels cars. The cars have now crossed the

auction

block, and all four we told you about brought in six-figure winning bids.

The most expensive of the four was a 1970 Plymouth Road Runner, shown above, that sold for $341,000. It featured a tri-tone paint scheme, custom rectangular headlights, full-width, single-piece taillight, a molded-in rear wing, slotted mag wheels and a big Road Runner decal down the side. Under the hood was a 426-cubic-inch Hemi V8 with an automatic transmission.

Bringing up the rear was a 1969

Dodge Dart

Swinger with a sale price of $110,000. The lower price may be partly because it wasn’t technically a Rapid Transit car, but it was a factory custom from

Dodge

that was on the stand at the 1969

Chicago Auto Show

. It features a mellow paint scheme, but unique touches such as the rectangular headlights, inset fog lights, integrated door handles and that enormous (and unfortunately fake) hood scoop. We wouldn’t remove that scoop, though, since Dodge put it there itself. Like the Duster, it had a 340-cubic-inch V8 and four-speed manual transmission.
