I have a 94 toyota w/~120 K on it, and here are some things you might want be aware are very common problems on Toyota engines (truck engines)
The timing chain can slap into the guide and break the holding pins, which as something like $1400 to fix in a good shop. A mechanic good with toyotas can hear it pretty clearly. Also have em check to see if the clutch is new. A clutch with 115K on it will need repair very soon.
Mine also had a radiator leak, but that was a long time ago. Toyota might have upgraded the radiators.
