no harm in checking it out if it's close by. there is a rip in the drivers seat cloth but I'm assuming you saw that/it's not a big deal for you. some things I'd check

- there are no service records for 2 years
- does the AC work. noticed there was a freon top up in 2016. there is a chance you might not have AC / have to put up some cash to replace any leaks, not cheap
- make sure transfer case engages. it's a part time 4wd. consensus is that part time should be driven in 4x4 mode every now and then
- frame rust
- take a close look at the engine bay for any signs of leaks or any suspiciously clean areas that seem 'too clean' as if a leak has been cleaned up

personally I would pass on that one, but that's just me. sure you could take it for a PPI but sometimes those can be hit or miss. you really need a trusted mechanic for this one if you're concerned about engine issues
