If the Thunderbird sales numbers were stalled, what would the Corvette numbers be called? Definitely worse than stalled but GM bit the bullet and stayed with it. Unfortunately for the two seater Thunderbird and to McNarmara’s credit, the 1958 Thunderbirds out sold the previous three years of T-Bird production added together. That pulling out of racing in 1957 was definitely a miscue in my opinion but that also came at a time when FoMoCo was spending an incredible amount of money on new engine development, complete body redesigns across the board, and the Edsel lineup. It’s hard to say what the Ford cars would have looked like today if the two seater T-Birds had remained in the lineup instead of going to a back seat model.
