Looks fine.
Yes, not alot of online sources however I believe it's a situation where Quantity cannot beat Quality in this case as most all of those sites have extensive information on maintenance & upgrades from mild to wild.
As for whether to buy this particular rig, it all depends on how solid it is.
Engine, Tranny, & Electrical are the key things that come to mind.
Valve Guide Seals / Engine
Pretty much all Mitsu v6 engines in their 4x4's suffer from Valve Guide Seal issues at some point. The worse it is, the sooner you'll have to have them replaced. To check the condition, allow the rig to idle for 3-5 minutes or so. Rev it (say 3000 rpm) and check for smoke out of the tailpipe. If it has a valve guide seal problem it will have oily black/dark blue-gray smoke out the tailpipe. If it's white, or lt gray, run away.. that's likely a head gasket problem.
Belts/Waterpump
Hopefully the belts & associated hardware (water pump, tensioners, etc.) have all been replaced in the last 60k. If not, factor in $700+ for that.
Transmission
Tranny and xcase are pretty bullet proof but check for very slopping shifts after the engine & tranny are warm (run away if you encounter this).
Transfer case / hubs / Transfer case locker/rear differential locker
Also check for 4wd operation. Put in 4Hi. Drive forward. The front wheels should light up. Put in 4Hi Lock, and dive forward. The xcase lock light should light up.
Put in 4Lo Lock and depress the rear differential locker switch. The rear differential should light up (orange IIRC) indicating a locked rear diff.
Usually there are no issues with these items.
Now, turn the rear locker switch off & put it back into 2wd and continue driving forward (less than 45mph) and the front diff light should shut off as will the diff lock light and xcase lock light. If the front lights continue to flash it may be the vacuum line is broken or the sensors are dirty or need to be replaced.
Interior
As for the interior, if it's an SR, then it should have leather. Unfortunately the leather will likely be very worn on the driver seat and worn to some degree on the other seats. In mine, the driver seat was toast while the passenger seat was nearly new and the rear seats (both middle and 3rd row) were pretty much mint.
HTH.
