Depending on the year, the odometer may not go past 5 digits, so make sure its not 150k. Take a good look at the frame underneath and the floorpans. Mine rusted out long ago and were hillbilly repaired by the po. Check the gauges, etc. Crank the wheel all the way to the left and al the way back...listen for clunking,etc. Head over to jeeptruck.com for lots of comparison opportunities.
By the way...you live in Waynesboro! I'm in Verona. A rust free ride in good condition could easily go for $5-7k. I bought mine with a good frame, good mechanics, but poor body for $1500, so a solid body is a big deal. If you pass it up, let me know where i can find the ad, please, id be interestded to look, but would not want to cut in line. :-)
