Steve,I had heard 1500 combined too, but I don't think anyone knows for sure. I didn't see the other posting about this article until after I posted mine :-) . I was around in 57 and bought a new 57 convert, D Code, and I didn't see very many E or F code cars around the Chicago area or at the drag strips in Northern IL, WI and Indiana. Notable exception was George Chaltins F Code Skyliner. I did see a two tone green Fairlane 4 door F Code at a dealership in Oak Park, IL.
