How To Interpret Jeep Codes / What Jeep Codes Mean
What's a CJ5? Or an XJ? How are these codes interpreted to represent various models of Jeeps? 

While Jeep owners would likely tell you, "If you don't already know, then it's not important." The truth is, even diehards had to learn how to interpret these codes for the first time.
