I'll probably get jumped on for this, but for what they are, how they are are built, and the price they sell for, the Jeeps really aren't all that bad. Are they in in the same class as a 'cruiser? or even a 4Runner? No way, but then they start at about 1/2 the price new, and even less used..
I just got rid of a XJ with 320,000 km on the clock, and other than a couple of sets of front U-joints, all the rest of the parts that ever went into it were normal wear parts, like brakes and shocks. The engine was still running fine, lots of power, and would burn less than 1 litre in 5000km between oil changes....Yes, the doors had to be welded back on, and the rear main seal was changed when the clutch was changed at 250,000km. A 'Cruiser it isn't, but I basically paid the same for it as I did for my HZJ73, and it was 2 years old at the time, not 15, and had fewer km's on the clock. (Hell, it's still 4 years newer than than the 'Cruiser)
The Jeep didn't rot away with-out rust-proofing, and didn't need the BEB's done. And I don't expect I'll pick up front rotors for the 'Cruiser for less than $20 new, like the XJ.
