I've located a 1986 MJ, 4x4, 2.8, auto, 80,000 mi, all original. Body is in pretty good shape just your usual wear with age, no visible rust or body repair. Interior is good. Assuming engine all drivetrain components work as they should what would you estimate the value at? The asking price is $3800. I went to both KBB and NADA and of course the don't go past 1990, so they were no help. Is there a online price guide for these MJ's?
