I wave at all Jeeps but I Agree the 4 door JK gets the least return on investment. If I get a wave back so be it. It is like a neighbor we have my wife is determined to wave at him every time she sees him but he never waves back.
I just got my JK and the guy helping with my paper work told me about the wave. On the long drive home from Ohio everyone was waving but when got home to Atlanta no one except people with mods wave but I still do I have only had it about a month and a half
