I don't know about the 60,000 mile service but major maintenance service I've been quoted at around $400. It really depends on what they are doing. $600 is rather high IMO. There are minor and major service and of course the minor service is less money. Some shops will add service that you don't really need to increase the cost so check your owner's manual and see what you need done at 60,000. Make sure you actually know what they are going to do before they do it so they don't charge you $400 just to change the oil.
