If GM brought the Chevelle back, it would be a 4-door (some of the older Chevelle's were 4-doors

, believe it or not). It would be a similar idea to the Charger of today. A 4-door would sell better because it's more practical. The Corvette and Camaro are enough 2-doors for Chevrolet. Heck, even the new Sonic (Aveo replacement) isn't available with a 2-door model.
