My great uncle had a low mileage early CJ-5 jeep that was rarely used and rarely left the farm (sold before his death; sadly I couldn’t get it at the time). So, it’s possible the 8200 mileage is correct. However, with that low of mileage, I’m surprised the heater (or whatever was installed on the passenger side — see engine compartment photo — isn’t still there).

“This Jeep is completely original. It has 8200 original miles. It spent most of its adult life in Eastern Wa. Everything works…4 wheel drive..runs well. Has always been garaged.”
