First of all trailin or four wheelin or whatever you call it is meant to be fun. You are to enjoy yourself, the rig your in is built up to meet your enjoyment factor. You can buy a good condition xj for under 5 grand, I do't know the sticker on a kj, but it is near if not excess of 30 grand. Look at this difference. Parts are available to modify a xj, parts are now being made to modify a kj. Example I'm on a banked dirt trail lined with trees, my rig slips and i hit the tree against my side. Which vehicle will i be more upset about the 5 grand xj or the 30 grand kj. Why take a kj trailin now so early in their lives when their are wonderful xj that need little modifying to have a wonderful time in, plus to fix damage on a xj is so much easier than on a kj.
