One-Of-None 1970 Plymouth Barracuda Sedan Heads to Mecum Again

When you think of a 1970 Plymouth Barracuda, chances are a snarling two-door muscle car comes to mind—maybe a HEMI, maybe a Six Barrel. But what if someone built a four-door version? That’s exactly what the late Dave Walden did, and now his one-of-a-kind creation is set to hit the auction block at Mecum’s Spring Special 2025 in Florida on Saturday, July 12th.

This isn’t a rendering or a concept sketch—it’s real steel. Dave Walden, founder of ECS Automotive Concepts and a legend in the Mopar restoration scene, hand-built this one-off four-door E-Body as a tribute to what a production Barracuda sedan could have looked like in 1970. And it looks like the real deal.

Starting with extensive custom metalwork, Walden reshaped the roofline and doors to mimic a factory-style four-door layout. No fiberglass or shortcuts here—just expert craftsmanship and vision. Even the VIN is unique, ending in “1000000,” separating it from typical Chrysler production norms.

Power comes from a 5.6-liter (340 cubic-inch) LA-series E55 V8 rated at 275 horsepower, backed by a classic A727 TorqueFlite automatic transmission. Walden also fitted the car with power steering and power disc brakes up front, making it as drivable as it is rare.

Painted in factory-correct FE5 Rallye Red and topped with a black vinyl roof, the car rides on chrome 5-spoke wheels wrapped in redline tires. The interior is just as dialed-in, featuring a black bench seat with center armrest, tilt-telescopic steering wheel, in-dash clock, rear courtesy lights, and a one-off set of custom door panels. It’s got all the subtle factory details, including Barracuda script badges and a proper chrome wheel lip moldings.

This car originally debuted at the Specialty Equipment Market Association (SEMA) Show in 2016, but it didn’t touch pavement until 2022. Included in the sale are a Mopar product catalog, vanity plates, a reproduction window sticker showing redelivery to Chrysler, and a fake-but-fun broadcast sheet imagining how it would’ve rolled off a Chrysler/Plymouth assembly line.

Expected to fetch somewhere between $200,000 and $300,000, this is the third time this one-off ‘Cuda has crossed the auction block in two years. Let’s hope this time it finds the right garage—and someone who appreciates just how special it really is.
