The list price on a new 1976 264 was $8,450, which was about $37,000 in inflation-adjusted 2017 dollars. This was a few hundred bucks less than a new 1976 Oldsmobile Delta 88 Royale sedan, complete with V8 engine and several hectares of fuzzy crypto-velour upholstery.
Power came from an overhead-cam, 2.7-liter PRV V6, rated at 123 horsepower. This engine, developed jointly by Peugeot, Renault, and Volvo, went into a bewildering assortment of vehicles (e.g, the DeLorean DMC-12, the Alpine A310, and the Eagle Premier) during its 22 years of production. The four-cylinder engine installed in the 1976 242/244/245 made 98 horsepower, so the 264 was a bit quicker.
This one didn't quite make it to 150,000 miles, and the sun-bleached interior and top-down rust on the exterior suggests decades of outdoor storage. Perhaps something expensive broke, back in the 1980s or 1990s, and the car sat awaiting repairs that never came.
