I am interested in purchasing a 57 Cheverolet. All I know about the car is ..I was told that it is not a Bel Air but, it is one step under. I was told that Cheverolet made 3 cars during this period. The luxury car was called a Bel Air. The next one was just a Cheverolet was some upgrades and the last one was just a basic car. Can anyone direct me on how I can find out this information.
