Series 75 Cadillac Models & History 1948

Onthe Series 75 Fleetwood, consideration was given to the deletion of the long-wheelbase line this year, but competitive pressures from Packard in the luxury class market dictated the retention of these models. Again, they featured General Motors’ old fashioned “Turret Top” styling, a throwback to the pre-war years. Minor revisions on the outside of the cars included a new background for the V-shaped hood emblem and Cadillac scripts — replacing block lettering — low on the fenders behind the front wheel opening. Buyers ordering fog lamps got rectangular parking lamps in place of the smaller round style. Stainless steel runningboards were seen once more and the 75s also had the new dashboard treatment, but with burled leather trim.
