It looks nice... are those rock bars or just steps?
Something about the 4.0L timing chain/belt? Different engine than what I have.
Would be interested to know if cruise buttons are good since that seems to be always worn out but easy to change.
Other guys will know a lot more technically what to look at. But certainly you know the basic stuff... is interior ok, does it drive/shift good, doesn't pull to the side steering/braking, does all fancy electric stuff work, a/c, heater, blower, what's engine bay look like, is there lot of rust underneath, door jambs, etc. Funny noises on startup/running, exhaust leaks, etc etc I have a feeling you know all this.
If tires are worn talk it down on that; you might want to change them anyway depending.
Then there's one test that isn't really quantifiable, I just do a "feel" test.... do I like it, does it feel good to me, do I feel like, I'd like to go places in this?
Granted that's totally unscientific but I look at it this way, if it doesn't feel right to me now, why would it later. Unless it's something you put your finger on like unbalanced wheel, etc.
Get Carfax and see how many owners and where. It's 20 years old, so did it have, like, one or two owners (they must have liked it) or did it have like five or six owners which -might- make you say, hm, nobody really kept it all that long.
Get the Oasis if you can see what was done on it. And don't feel like, darn, I drove here, I might not see another one.... you will... there's lots of them. Maybe lower mileage ones.
But it does look nice and if good shape and the options you want and price is good then it could be the one.
Cap is worth something, if you like caps. Should have bedliner(?).
