‘Though inspired by, and positioned directly against, the Chevrolet Corvette, Ford billed the Thunderbird as a ‘personal luxury car’, putting a greater emphasis on the vehicle’s comfort and convenience features rather than its inherent sportiness. The Thunderbird sold exceptionally well in its first year, outselling the Corvette by more than 23-to-one for 1955 – 16,155 Thunderbirds sold against 700 Corvettes. With the initial Thunderbird considered a success, few changes were made to the car for the 1956 model year: the most notable alteration was a new 12-volt electrical system and a shift of the spare tire to a continental-style rear bumper to make more storage room in the trunk.
