I bought my 2000 XJ with 250,000 miles on it, I have put over 10,000 on it and it still runs as good as any Jeep I have ever owned. I curently have a 97 XJ with 115,000 on it, my 2000 XJ with 260,000 has more power, gets better mileage, and dosn't have any problems. Only non maint. part that has ever been replaced is the AC compressor. The rear main seal drips but it is not bad at all, run it till it dies then stroke it!
