Plymouth never sold a four-door Barracuda, but that didn’t stop one dedicated Mopar enthusiast from building one. This unusual 1970 Barracuda-style sedan looks like something Chrysler might have produced decades ago, and it’s currently up for auction on Bring a Trailer.
The car was created by the late Dave Walden and his team at ECS Automotive Concepts, who wanted to explore what a factory-built four-door Barracuda could have looked like. Rather than simply stretching an existing coupe, they went to extraordinary lengths to make the finished product appear authentic.
Completed in 2017, the custom Plymouth was displayed at that year’s SEMA Show and featured in Hot Rod magazine. Its Rallye Red paint, black vinyl roof, and period-correct details make it look surprisingly convincing.
Despite its factory appearance, this is a one-off creation rather than a forgotten production model. The selling dealer acquired it in September 2026, and it’s now looking for another owner.
Building The Barracuda Chrysler Never Made
The project was partly inspired by an account from a former Chrysler employee who claimed to have seen a four-door Barracuda prototype in 1969. Walden decided to turn that intriguing piece of Mopar history into a functioning vehicle.
The build incorporates the modified roof and pillars of a 1972 Dodge Coronet sedan, while much of the remaining bodywork was custom-fabricated. Its wheelbase is 10 inches longer than a standard Barracuda’s, with specially constructed rear doors and modified fenders, bumpers, and hood.
Walden reportedly estimated that only 10% to 15% of its components would interchange with a production 1970 Barracuda. That gives some idea of the work involved in making the car look like a genuine factory model.
A 340 V8 And An Authentic-Looking Interior
Under the hood sits a 340-cubic-inch (5.6-liter) V8, reportedly rebuilt to 1970 specifications. It’s equipped with a Carter four-barrel carburetor and paired with a rebuilt TorqueFlite three-speed automatic transmission.
Inside, the sedan features black vinyl bench seats, an AM radio, and a woodgrain steering wheel mounted on a custom tilt-and-telescoping column. The rear doors open to reveal a fully finished passenger compartment.
Walden even created period-style paperwork, including a window sticker, broadcast sheet, and identification tag. These documents were fabricated for the project rather than issued by Chrysler.
This One-Off Plymouth Is Up For Grabs
The five-digit odometer displays just one mile, suggesting this unusual creation has seen very little road use since its completion. The car comes with a Pennsylvania title describing it as a 1970 Plymouth four-door.
At the time of writing, bidding had reached $40,000. Previous auction results suggest its value has fluctuated considerably, with Autoevolution reporting sales of $121,000 in 2023 and $54,880 at a later auction.
For Mopar fans who have wondered what a four-door Barracuda might have looked like, this unusual creation offers a remarkably convincing answer.
