That's a good deal. I bought my 05 rubicon with 114k for quite a bit more but from a dealer.
I'd have the mechanic literally check everything. Gears, lockers, tranny, belts, color of all fluids so you can get an idea if it has been changed and taken care of.
Lots of people look at the outside and easy stuff. But it's the gears, lockers etc that are expensive. Checking the fluid making sure it's not molasses or super bad allows you to get inside the jeep and see if it has been truly taken care of.
Anyways. Off my rant lol
