1997 was the first year of the TJ, I know they have made some changes, but nothing major if I remember correctly. 5K seems to be about right, hard or soft top? any extras? or is it completely stock? Stock might not be bad as that will probably mean it has only seen highway miles with little offroad. No AC is a bummer, but if it is only a second car nothing to worry about. Good idea having a mechanic look at it. Ask for any paperwork on maintenance.
