Depends on what you want to do with it and how well you like to work on your own rig.
97.5 and 98's are the best years to go after due to the many upgrades that were done over the earlier 90's. 99 and up have ABS and TT4 traction control which many offroader don't like.
I have a sweet 98 soft top for sale and can be contacted at
