General Year Information

1947 Buicks were, for the most part, unchanged from their 1946 counterparts. A new stamped grille with a separate upper bar distinguished 1947 Buick’s from their 1946 predecessors. Interiors featured round gauges with control switches flanking a center grille on the instrument panel.

Post-war cars were selling like hotcakes as the car-hungry population snapped up what was being offered. As a result, Buick production increased from 1946’s 149,395 to 260,934.
