Rare 1970 Plymouth Barracuda Slant-Six Convertible Heads to Auction

Plymouth gave the Barracuda its own dedicated platform for 1970, finally separating it from the compact Valiant architecture it had borrowed before. The move paid off at the sales desk, with volume climbing roughly 50 percent over the previous year. Yet within that successful run hid some genuinely scarce variations, and a Slant-Six convertible paired with an automatic transmission sits near the top of that list. The seller claims only 158 such cars were ever built, and this particular example remains with the person who bought it new.

The 1970 Barracuda rode on the same underpinnings as the Dodge Challenger, which also debuted that year, though the two shared no body panels and even differed in wheelbase. Close to 50,000 Barracudas left the factory during that first year, a figure the model would never match again as the muscle car boom faded and both it and the Challenger were axed in 1974.

Offered out of Jacksonville, Florida, this Mopar wears Rallye Red paint resprayed back in 1980, now showing assorted chips, small dents and some bubbling along the rear quarter panels. The odometer reads 82,000 miles, the TorqueFlite automatic has just been rebuilt, and the engine appears untouched. Recent attention also went to the brakes and suspension, along with fresh tires. Inside, the black cabin is factory-original, though the driver’s seat is worn and the dash carries a crack. The white canvas roof is original too, but the boot cover has gone missing. Power steering and power brakes should make it easy to handle, service invoices are on hand for the next owner, and the leaky muffler will need replacing.
