Hi, Ive been spending some time here researching. Im lookin at a 91 yj with 6 cyl auto. The good part about this jeep is that the body and interior are in great shape. Paint is great, seats are flawless. The downside is that it has about 190M on it. Theres a lot of oil buildup around the valve covers, esp the front. The diffs look like theyre leaking a little bit and the transmission too. (Im hoping that its just a matter of changing the gaskets?or am I being overly optimistic?) No rust, no apparent body work or evidence of accidents. I know that the values of these jeeps vary depending on location. Im located in So Cal and was wondering what you guys think of this vehicle and what a fair/good price would be for me if I were to buy it or should I avoid this one because of the apparent leakages and mileage. Thanks to any and all advice. This is a kick ass site.
