I'm not going to say there is definite evidence of something funny going on there, but there are some things that stand out....
It appears there are additional coatings added to the frame, just looks too sloppy for original. Maybe a means to protect.
Interesting how the bolts on the TRE's widely vary in their rust/surface rust...
While I understand replacing belts due to age (and not mileage/use) as rubber cracks, it seems odd that the HG's were replaced but the radiator hoses weren't...
Don't get me wrong - it's a very nice vehicle. However you see this in the FJ40 world as well, where the pictures tell a slightly different story than what you're being sold... then those who REALLY know the vehicle will rip it apart. Not sure there are as many fanatical individuals for T4R's (esp 2nd gens) as there are FJ40 guys - who can see a bolt, latch, bulb, wire and say "that isn't original for that year".
