$400 sounds pretty reasonable.
Make sure all fluids (except power steering) and filters (micro, fuel, air) get replaced, wiper blade inserts, seals and hinges lubed, bulb check (if you still have marker lights -- amazing how many times those bulbs get overlooked because they're not covered by the check control). And it's always good to check that quality parts and fluids are used, especially in the diff and trans.
Beyond that, it's a systems check, and if your guy is any good, he'll find what needs to be found and not take advantage of you on what doesn't need to be found.
Good job for thinking to do an inspection II -- most owners decide the car's not worth maintenance after 99k.
