XJ NEWBIE

Okay here's the deal. I am new to modifying my XJ - not new to the XJ. My Jeep is still a baby mile wise - only 115K and still runs like a top, bought it with 39K 8 years ago. Trying to figure out where the most bang for buck is going to be. Not a big offroad fan - but love the look of those of you that have put the time and bucks into your rigs. But first things first - I have a hinge issue with my front driver's side door. The weld has failed and is now dangling there. I'm sure I'm not the only one out there with this problem - Looking for some feedback. Also has anyone ever installed the THOR rear quarter body armor for their XJ (again like the finished look) -

ANY feedback would be great -

Thanks guys (and gals)
