While there have been a lot of outlandish concept cars that have ended up going into production (we’re looking at you, Pontiac Aztek), there are also plenty that we wish were produced on a larger scale but never quite made it to the open road. This 1971 Plymouth Road Runner Rapid Transit fits squarely in the latter category. But there is some good news: the prototype is headed to the auction block.
Built by Chuck Miller of Styline Custom in 1970, this one-off American muscle car was a part of Plymouth’s traveling road show. Despite all its traveling, however, its 383ci V8 engine has only 1,300 miles on the odometer and the whole rig is completely unrestored (but is still in exceedingly good condition). Along with that power plant, the ‘Chicken Head’ Plymouth also features a custom front end, a hand-formed rear roll pan with tri-color taillight lenses, a molded aerodynamic rear spoiler, black pan wheel covers, and the signature Voice of Road Runner horn. While no pricing information has been unveiled, you can expect to see this one-of-a-kind pony car go for a pretty penny.
