Cavalier model differences
interior and exterior badging would be the easiest if they exist. The engines are different. The Z24 had a 2.4 liter DOHC 4 cylinder, while all the other models used the 2.2 liter.
wait, what years are you talking about?
good point. I based it off of the 1997 model listed in the heading. Prior body design that ended in 1994 would be a little harder to figure out since the RS and Z24 only had suspension differences. Oh, and the Z24 had a factory fiberglass ram-air hood. Body cladding more prevelent on Z24's too.
