+1 for the 2000.
I'm partial to the earlier TJs and the manual trans. Like Jerry said, while the PCM fix is available, the OPDA issue is not really permanently fixable. You can find the updated part, but that isn't a permanent fix, it just lasts a bit longer.
The mileage wouldn't really scare me at all with a TJ. Condition and maintenance are more important. A 2005 with 42k miles has sat a lot.
Thanks, I am going up tomorrow and if it is as nice as the seller says I will bring it home. I know from one of my buddies that once you get into this jeep thing it is totally acceptable to pick up one or two more along the way! I have room for 5 vehicles, possibly six, without looking like a used car lot. I am presently at four (wife gets one) so room for at least one more right now. I will keep watching but if the 2000 turns out to be exactly right for me I may stop at 5. I may even consider selling my TDI, or my Powerstroke. Hard to believe I just said that.
