OBD Fusion/Link can scan most vehicle ECUs and is almost like portable Techstream. / perform your own scan of vehicle for issues. Check to see when codes were last reset as well. Seller could be hiding issues if codes were recently reset. While OBD readiness can be reset with a battery swap you can see how long ago that event took place.
Check to make sure the coolant recovery tank has pink coolant in it. If empty this could indicate leak.
On my 5 year old gen2 (2015):
- timing cover leak - manifests with some minor oil leak below the heads of the V8, at the side of the serpentine belt pulley, easier to spot on the driver side of engine, bad Toyota sealer during assembly
- water pump - 140USD in parts - watch out for an empty coolant reservoir, happens to most engines around 100k
- serpentine belt tensioner - 40USD in parts, happens to most engines around 100k
- dead battery - 5 years time, pretty normal
Other:
- engine valley coolant leak - not happened to me, but people mention about 1000-2000 USD in labor, happens because of a faulty Toyota sealer used
Damn Acrad, couldnt you become a mod and make these awesome stickers 6months ago?!

really hope to see more posts like this bringing up the smaller issues with these tanks.
if you live in the salt belt, apart from looking for frame rust, check under the doors for rust also.
