A YouTuber found a rare 1975 Plymouth Road Runner GTX, which is already a rare car to begin with.
But, on closer inspection, the YouTuber realized the car was even more special than he thought.
This is because this particular model was designed by Plymouth for promotional purposes.
They only made 25 in total.

What makes this Plymouth Road Runner GTX so rare
YouTuber Dennis Collins didn’t take long to realize this Road Runner GTX was special.
Barn finds involving Plymouths always make headlines, sometimes even more so when it’s found with $10,000 under the seat, which is what happened to another YouTuber.
But we digress, the point is this is a limited-edition version of a rare iteration of an already rare car.


In 1974, Chrysler, which was Plymouth’s parent company at the time, only built 386 Road Runner GTXs, including 25 promo cars co-designed with Mopar, which is what this is.
All 25 were finished in blue with matching interior, and each car was powered by the same 440 cubic-inch (7.2-liter) V8.


The difference between the Road Runner and the Superbird
Just like the Superbird, the Plymouth Road Runner draws its inspiration from the Looney Tunes characters Wile E. Coyote and the Road Runner.
After acquiring the rights to the name for peanuts (only $50,000), Plymouth launched the Road Runner in 1968 and the Superbird in 1970.
But while the Road Runner remained in production for three generations and 12 years, the Superbird only lasted one year.

This probably explains why this car is so rare these days that people are willing to spend six figures to buy one sight unseen.
The Road Runner is also quite rare, and collectors love it, but prices in the secondary market still haven’t exploded.
Even today, you can still find one in good condition for Tesla Model 3 or Model Y money, which is not bad.
