Cracking Jeep's DaVinci Code

Most people with a pulse know what a CJ is. Some have heard the term TJ. Not too many have heard of a VJ. And then just when you start to get the XJ, YJ, ZJ, and whatever-J designations down, Jeep goes and throws you a curve with the WK, the JK, and the XK? Are you joking? Nope. So to shed a glimmer of light on the subject, here is a little cheat sheet of which designation goes with which model. But don't go patting yourself on the back if you memorize it 'cause it changes again for the foreign market. Don't believe us? Just ask an Australian Commander owner about his XH.
