The big news at Chevrolet in 1929 was a new overhead-valve six-cylinder engine—the “Cast Iron Wonder” that would remain in production for 35 years. Chevy’s fours were previously called “National”; the new sixes were given the appellation “International.” Although Ford’s Model A, some $75 cheaper, outsold it, within two years the more sophisticated Chevrolet was out in front and stayed there, with few exceptions, for the rest of the century. Nineteen-thirty brought hydraulic shock absorbers, some minor changes to the windshield and instrument panel, plus yet another series name: Universal. There were ten body styles, priced from $495 to $685, nearly overlapping Ford territory.

This Chevrolet Universal AD coupe was assembled at the St. Louis plant. The third-most popular body style, after the two-door coach and four-door sedan, it came in base two-passenger form with trunk and disc wheels. A rumble seat and wire wheels were optional. Base price was $565. This car has the wire wheels, but not the rumble-seat option. Painted light green, its beltline molding is cream, matching the wheels, and subtly pinstriped in red. The upholstery is light magenta cloth, all in very good condition. Instruments include engine temperature, oil pressure, fuel, an ammeter, and a drum speedometer. An accessory Tropic Aire hot-water heater has been fitted. The engine compartment is very tidy and properly appointed. The wire wheels are mounted with 4.75 × 19 Allstate Safety Tread blackwall tires.

Although the Chevrolet coupe cost $65 more than Ford’s competing Model A coupe, the customer got two more cylinders, 10 more horsepower, and a much smoother ride. Within a year, Chevrolet ruled the sales sweepstakes.
