Here comes the questions. Does it run? How bad is the rust? where is the rust? what engine does it have? axles? tranny? wiring work? whats missing? how long has it been sitting?
My non-business, dedicated Jeeper side, says, "Hell Yea! $600 Jeep!!". Id say buy it if it runs(Or at-least if its not locked up, unless you plan on completely rebuilding the engine). What Ive learned is that you can use lots of money and do it quickly, or you can use Huge, enormous, copiously vast oceans of painstaking time, and not as much money. hahaha
