Thanks for the responses so far. It seems I am not getting value for 500 bucks, since the service does not include some of the items that you have listed.

Can you tell me what the change intervals should be for:
a) power steering fluid and filter
b) differential oil

The other question - I can just ask them to do oil change, tranny, air filter, plugs, check timing, and lubrication - these don't add up to 500 bucks! then why is the "package service" priced higher?
