2003 Toyota Highlander question about service choices

What do you think of taking car to Napa as opposed to Toyota Dealer to get maintainence and work done? Did so and cost of work has gone from $400.00 for 4 tires and brake pads to over $l600.00 and five days so far without car.

Have no idea how to answer that question. You do not say what work is being done and you should have approved it. Dealer prices are usually higher but not always. Napa facilities are not all the same so there is not a set answer.
