So I've stumbled across a virtually rust free 1996 Trooper Limited. Which in Michigan is pretty rare. I checked it out today at lunch but didn't have time to go for a test drive. Body is decent shape for a 20 year old truck with 176k miles. Everything works inside (heated seats, power mirrors ect.). The owner said something along the lines of the transfer case works but something came unplugged? Like I said I didn't get a chance to fully investigate. What should I inspect should I go forward with buying this truck? Anything to stay away from? Thanks.
