1957 Ford Thunderbird â?" Colonial White over Red, 312 V8, loaded with factory options, California car Why This Car Is Special The 1957 Ford Thunderbird holds a specific place in American automotive history that no other car can claim. It was the last year of the two-seat Thunderbird before Ford went to the four-seat 'Squarebird' body in 1958, a decision driven by sales data and executive pressure. Ford sold 21,380 units in 1957, making it the highest-production year of the three-year original run. Because of that transition, collectors have always placed a premium on 1955, 1956, and 1957 Thunderbirds â?" and within that group, the 1957 is the most refined version of the original design.
