1972 Chevrolet Impala

The 1972 Impala had a grille extending below the bumper, and variable ratio power steering became standard that year. From 1972 all engines were designed to run on unleaded gasoline. It was the last year of the Impala convertible, which sold 6,456 units and placed fourth in the market, just behind the Corvette at 6,508 and ahead of the Mustang at 6,401. The 250 inline six was still standard for the Sport Coupe and four door sedan, with 350, 400, 402 and 454 cubic inch V8s as options.
