keep looking
There are always jeep for sale I know that several years have serious issues with transmissions and there are a lot of places you can go to find out something about a puegot transmission or something. I would look for a mechanically sound piece before going with the yj I am sure you could fing a tj or wj for that price. and 120k on the cherokee is I think too much, Consider that for armor aesthetics and interior there are hundreds of product so don't get hung up on those items after all you are going to build it right?
