“This listing is for a 1947 Willys Jeep. The Jeep has been in my possession or my father’s position for a very long time. It was in my father’s garage in Prescott forever and we brought it down here to Phoenix. It has a new battery but needs some overall work. The engine will crank and start but does not keep running. Most of the items on the Jeep are not original – notice the newer wheels etc. However, the battery, upholstery and windshield are fine. Headlights, taillights and blinkers all work fine. It does not have the original engine – the original engine would have been a 4 cylinder. This has a 6 cylinder and I am pretty sure it is from a Studebaker. The odometer gauge does not work and it says 21,227 but I’m sure there are more miles on it than this. I am hoping to sell this to an individual who is into Jeeps – I don’t need help selling it and I am not looking to trade it in – so no dealer emails. Thanks.”
