Ok, this was an interesting experience.
1) Independent Guy around the corner, for the 60K service, as descrived above: $100 even. Told me the chances of him finding anything wrong with the car during the inspection are next to nul.
2) Dealership No. 1 (where I bought the car, under their Certified program): first quote was ...........

$540

!!! (same service, but they top all the fluids and look at the battery as well). I argued that this kind of service was already done not long ago when I bought the car under their "Certified" program and I've only driven the car 2000 miles since then, if that, and they eventually dropped the price to $135.
3) Dealership No. 2 (closer to where I live but with bad reviews on Yelp): $129 because they're having a special right now.
4) Dealership No. 3 (a little further, also bad reviews): put me on hold for a long time ... then I hung up.
5) Oh, and just for the sport of it, I went to another independent mechanic, about 10 miles from where I live, pretty highly recommended on Yelp:
Their price (they were thorough and gave me a computer print-out of what Toyota requires them to do for a Yaris that age, at that mileage (which is the same as what I typed above) $200.
Hmmmmm....
By the way, I have a Manual Transmission if that makes a difference.
