They seem to be good cars, one of our secretaries has one and has had no problems with it, likes it. She has about 110~120K miles as well.
One thing I will comment on is that Toyota A/T are *very* sensitive to over-filling. Beware any that have about a pint too much fluid in them - reasonably sure sign that someone has added a can of "magic elixer" in the vain hope of fixing some sort of leak or slip. What this *will* actually accomplish is ruin the main pump...
Never mind how I know this...
Certainly take a look into the oil fill port on the engine, you can see if it's clean or sludgy, at least to some extent you can.
