Plymouth died nearly two decades ago, but this rusty old convertible is probably worth more than your house.

Set to go under the hammer at Mecum’s Indy auction next month, this 1971 Cuda convertible is a rare breed as it’s an export model.

This makes it pretty unique as the auction house noted the export market wasn’t large and “this amazingly unrestored 1971 440 6-BBL Cuda is one of only two such cars from the final year of Cuda convertible production.” On top of that, this car is just one of “17 V-Code 440 6-BBL Cuda convertibles” produced that year.

While it’s clearly not in the best shape, the car spent 35 years locked away in a storage container. However, that didn’t offer much protection as the paint has faded and there are numerous rust spots. Despite this, the interior appears to be in relatively good shape and the “driveline and mechanical components have been refreshed.”

Originally is key when it comes to cars like this and Mecum says the vehicle is well documented and includes a broadcast sheet, a fender tag and a door VIN decal that is still intact. The model also has its original body panels as well as a 7.2-liter V8 engine with a six barrel carburetor.

Other highlights include a Tor-Red exterior with a contrasting black top, rallye wheels and a “Go Wing” rear spoiler. There’s also black bucket seats, a “Slap Stik” shifter and a TorqueFlite automatic transmission.

The car is expected to fetch between $500,000 (£401,250 / €444,018) and $700,000 (£561,855 / €621,625) and this makes Dodge Challenger SRT Demons look relatively affordable in comparison.
