My very first check-over of anything that comes in my garage is fluids/undercarriage.
Don't worry so much about the little stuff, you can fix that over time.
Any fluid/undercarriage/engine/transmission stuff needs to be taken care of ASAP, because those can all snowball into deeper issues.
You scored good!
LJ's with the description you posted are going for around 14-18k in my area.
I would have paid $10k for what you said, If I could have found it!
I wish either of my two were Automatic!
I love driving manual transmission, but damn am I doing chores on the trails, while everyone else is lolligagging up the rocks.
