The Buick Century models built between 1936 and 1942 were true high-performance cars, capable of delivering speeds near the 'century mark.' They combined the largest and most powerful Buick engine of the time, a 320-cid straight-eight, with the smallest and lightest Buick bodies then produced.

All 1939 Buicks featured new styling, with a low, wide 'waterfall' grille that was inspired by European Grand Prix racing cars of the era. Century models for 1939 had a 126-inch wheelbase, five inches longer than the Special of the same year. The extra length was added ahead of the cowl, to accommodate the larger engine used in the Century.

The Century Convertible Coupe, Model 66C, had a factory list price of $1,343, making it the most expensive Buick of its type in 1939. Only 850 were built, including 60 that were exported to other countries. The exhibited example is equipped with optional dual side-mounted spare tires, 'Streamboards' (lower body skirts which replaced the standard running boards) and a pair of GM Guide Super-Ray accessory driving and fog lamps - original cost, $10.45!
