Thank you for the correction and great advice.Since you are a new member, your comment -'Not a great year" will be merely sneared at.
2003's had the oil pump issue, many had engines replaced, and no locking t-case.
The 2004's had the latest SLABS, locking t-case, etc.
Offer $500 for starters, 'cuz your going to do the head gaskets and replace all the other stuff that's been sitting since they parked it. And that's a lot of stuff.
Worst case, they drove it and overheated the engine. in that case, you have some engine options, as long as you aren't in Calif.
