What to look for on a ZJ
 

Hi all, a friend of mine is possibly looking at a ZJ local to us so I'm wondering if there's anything ZJ specific worth taking a closer look at. General condition and rust is obviously something to look for but are there any common issues worth noting? It has the 4l engine and auto box so is it the same AW4 in the XJ?

Thanks, any advise is much appreciated.
