One Family-Owned 1970 Plymouth Superbird Has Surfaced Outside The Registry

A long-hidden 1970 Plymouth Superbird has surfaced through the Mopars5150 YouTube channel, and this one comes with the kind of backstory collectors love. The car was reportedly pointed out by noted Mopar collector Tim Wellborn before the team made a stop to inspect it.

The white winged warrior has spent decades in one family and, according to the discussion in the video, does not appear in the known Superbird registry. For a car as closely followed as Plymouth’s NASCAR-bred homologation special, that makes the discovery especially interesting.

This particular Superbird is not a perfectly preserved museum piece or a freshly restored auction queen. Instead, it is a deeply personal family car with old paperwork, long memories, Daytona connections, and a hood covered in signatures from racing personalities.

The Mopars5150 crew eventually struck a deal to buy the car after confirming key identification details. As hidden Mopar finds go, this one blends rarity, documentation, and human history in a way that makes the car far richer than its spec sheet alone.

A Superbird With Family Roots

According to the owner, his brother purchased the car in June 1971 after trading in a Chevrolet Corvair. The original paperwork reportedly shows a sale price of $4,298, along with the trade-in details.

The car remained connected to the Harris family for more than 50 years. The owner explained that it passed from his brother to him and later to his son, keeping the Superbird within the family line.

That long ownership history is one of the car’s strongest assets. Plenty of Superbirds have changed hands multiple times, but this example appears to have stayed close to its original story since the early 1970s.

Daytona Memories And A Signed Hood

The car’s most unusual feature may be its hood, which carries numerous signatures tied to NASCAR and Daytona history. The owner said his brother lived near Daytona International Speedway in a house painted like a checkered flag.

That location reportedly brought him into contact with members of the Living Legends of Auto Racing and other racing figures. Names mentioned in the video include Ray Fox, while Richard Petty was also photographed signing the car.

Petty’s signature apparently was not preserved under clear coat and later faded, but the family retained newspaper evidence showing him signing the hood. The remaining autographs turn the Superbird into a rolling scrapbook from a very specific era of stock car culture.

Not Perfect, Still Important

The Mopars5150 inspection found plenty of positives, along with some issues expected from a car that was actually used. The fender tag is missing, although the owner had a build sheet and other documentation.

The car was described as a white 440 four-speed Superbird with a black interior, bucket seats, buddy seat, AM radio, and Dana 60 rear axle. The crew noted that the engine block was not original to the car, though it appeared to be a genuine 440 Six-Barrel engine from another 1970 Mopar.

There were also signs of older bodywork, including repairs around the quarters and nose area. Even so, the trunk VIN stamping was located and matched the car, which was enough for the buyers to move forward.

A Wing Car That Was Actually Driven

Unlike many modern collector cars, this Superbird lived an active life. The family recalled using it around Daytona Beach, taking trips, cruising in Kentucky, and even teaching younger family members how to drive a manual transmission.

The car had reportedly been in Alabama for decades and had not been shown publicly. That explains why even local Mopar enthusiasts were surprised to learn it existed nearby.

Despite brake issues and a flat tire, the Superbird fired up during the visit and was moved under its own power. That moment reinforced what makes these cars so magnetic: even tired and dusty, a Superbird can still stop people in their tracks.

A Rare Mopar Find With A Human Story


Plymouth built the Superbird for one model year to satisfy NASCAR homologation rules, giving it the pointed nose, towering rear wing, and big-block hardware that made it legendary. Today, any authentic example is valuable, but an unregistered family-owned car with this kind of history is especially compelling.

This Superbird may need sorting, documentation work, and mechanical attention, yet its personality is already fully intact. Between the long family ownership, Daytona ties, signed hood, and rediscovery by Mopars5150, it has the kind of story no restoration shop can recreate.

For Mopar fans, the best part is that another real Superbird has come back into the light.
