Theres a lot of custom work done, but was it done correctly? What year small block? Mileage on the engine? Mileage on the transmission? Dana 60 axle...like an aftermarket "pro rock" from dyna trac or something thrown together from a junk yard?

If you are planning on unloading it after the trade to make a few dollars, the market is gonna be slim. You will have to find someone looking for a jeep on 40's with a small block. Those kind of mods are usually hard to get your money back out of, unless you find the one person looking for what you have built.

edit:How long has the current owner been trying to sell it? That might give you an indication of why he wants to trade.
