Thanks for the welcome guys. And thanks for clearing things up for me also!
I spent most of the day looking around town and made a small trip to check out one that caught my eye in a neighboring town. This is the add off of CL.
2003 Jeep Wrangler X Sport Utility 2D
I took the wifey down and looked it over, and really liked it. Took it for a test drive and it drove great. No rust issues underneath...some slight surface rust on the inside behind the back seat under the carpet but I guess the old top leaked some so there's a new top it now. Shifts good, 4wd works great. Over all pretty happy with it. The lot has had it for almost 4 months and I bought one of my Mustangs from this same lot about a year ago so they remembered me (hopefully that helps when if I decide I like it and want to get the price down).
So as I understand it...a SE would be a base model followed by the X, then Sport, then Saharah, then Rubicon?
