Your definitely not getting a Rubicon on that budget, at least not a good one. Might get you a used TJ in questionable shape. That budget will get you a good older Honda CRV or Toyota RAV4, if you look long and hard. Cheaper on gas and more road height than passenger cars.
I'd sell you my 1990 Cherokee for 10K. Jeeps are worth their weight in gold here.
FWIW, Vehicles on Supercarros tend to run higher than vehicles on free local classified websites. There are 3 Wranglers for 10K or less right now, but they are all 4 cylinder models.
