As state-of-art, carbon-fiber rocket cars screamed qualifying laps inside the Circuit of the Americas road course, throngs of F1 fans gawked at the machine parked outside the track. It was heavy, and steel, and old. Yet, next to the likes of Ferrari, Mercedes, and McLaren, it might have been the prettiest vehicle at the venue.

That’s because despite the pinnacle of engineering and speed on hand, no other car boasted the classic American muscle heritage. Arguably the most iconic of the big-engine, big-body muscle era, the 1973 Barracuda is a rare mix of beauty and beast. And this particular Barracuda was even more distinguished among its lineage, thanks to some modern technology and a little McLaren magic.

Part of a project to highlight the capacity of the eBay Motors marketplace — and boost the buzz for the McLaren F1 race team — this ’73 Barracuda not only used parts and upgrades sourced exclusively from eBay Motors, but it also received McLaren’s exclusive “papaya” orange paint job and a signature from the team’s star driver, Lando Norris.

Now eBay Motors and McLaren Racing want to capitalize on the buzz to do some good and send this modern classic to one worthy auction winner. Beginning today, you can bid on the one-of-a-kind Plymouth Barracuda restomod on eBay. All proceeds from the auction will benefit the Society of Women Engineers, a nod to the car’s chief upgrade mechanic, Alex Taylor.

eBay Motors Auction: Restomod Barracuda

While the original car was in good shape and “already heavily restored when eBay purchased it,” according to Taylor, she still put in plenty of hours to truly modernize the muscle.

Highlighting the upgrades are a coilover conversion for front and rear suspension, forged front and rear disc brakes, performance headers and exhaust, updated headlights and tail lights, a wood steering wheel, and race-inspired bucket seats.
