The Chevrolet Fleetline was produced from 1941 to 1952. It was available in both four-door and two-door “Aerosedan” models.
The Fleetline was popular and comprised over 70% of Chevrolet’s sales during its production, although there was a pause in their manufacturing during WWII years. In 1945, production normalized.
Fleetlines are popular and collectable and are often converted into street hot-rods, using the Chevrolet 350 small block V8. This was a particularly nicely preserved specimen I spotted in Calgary.
