That's probably true as a rule, but not all dealer service departments -- or dealers -- are equal. You'll probably pay about the same anywhere for manufacturer-specified interval services, but as for the rest of it, the "screw factor" varies widely. Some places look at you as a cow to be milked, others want you to buy your next car there and do business accordingly. I've been pretty happy with the particular Honda dealer where I have the maintenance done. Having said that, I'd have no qualms about going to a good Japanese-import independent shop, were I to find one I'd trust to know as much about the car as the dealer guys do.
