The Chevrolet One-Fifty (or 150) was the economy/fleet model of the Chevrolet car from 1953 to 1957. The One-Fifty was mainly conceived as a fleet model and little effort was spent marketing it to the average car buyer of the day, although sales weren't limited to fleets. It was most popular with police, state governments, small businesses, economy-minded consumers and hot rodders. Chevrolet sold substantially fewer One-Fifties than Two-Tens or the Chevrolet Bel Air in every year of its life. Two generations of the 150 were built: 1st Gen (1953-1954) and 2nd Gen (1955-1957).
