Just purchased mine in 12/12 with 99k. So far, only had the power steering line replaced and, after much back and forth, the 'service 4wd' light replaced under warranty. As long as the Jeep has been taken care of and you replace the normal things at 100k, it should last you for quite some time. Just make sure you do your homework and get a feel for them. Plenty of info on this forum if you ever have an issue.
Depending on your needs, I'd go with a limited or an 06 Overland for an upgraded interior and a few more perks.
