1959 Pontiac Bonneville Convertible | Old Car

1959 Pontiac Bonneville Convertible. The 1959 Pontiac Bonnevilles became “Wide-Tracks” for 1959 — big but uncommonly handsome all-new cars that could fly like scalded bats and cornered better than anything else in the medium-price field. It was the start of what would be a dramatic upturn for a traditionally dowdy brand, which moved from sixth to fifth in the sales race.
