Your experience with "Free maintenance"
This was one of the benefits of my new Prius. I'm at about due for a maintenance check, and wonder if the dealers just use this as an opportunity for finding something wrong with the car, or if there are hidden charges. On my first Prius, I used to have these checks done by the wonderful folks who change my regular/snow tires. There were rarely any surprises, and costs for filters, fluids, etc. were very reasonable.
What's been your experience?
