My best bit of advice is that you throw the wrenches in the air, do a quick 180 and run, run, run. This jeep life is not the way to go. UNLESS of course, you enjoy hours of working on it, spending your life savings on it, begging the wife for time and money for it. And the thrill that can only come from driving a jeep. wheither that is on the street, the mountains or the red rock. If you can deal with these things, your in for the hobby of a life time. I bought my first new in 1981, a cj5 sold it cause of car pooling, DUMB. bought a 76 cj7 that I ended up giving to the son in law when I bought a 83 cj7. moved out east after selling the 83 and I'm currently raising a 1989 wrangler 4.2 back from the dead.
As you can see I have never owned something that new so I can't help you with the technical thing. But,,, welcome to the crazy life. you'll love it. I just hope your wife is Jeep Crazy like mine.
