Don't want to make you sick or anything, but check the list of what was included in the "basic service package" - normally it includes the oil change and "checking" a lot of things - things like if your steering wheel turns easily side-to-side, if your belt is worn, if the door hinges need lubing, etc. Some folks translate this to "dealer profit". A word to the wise - it's always better when you go into the dealer for one of the routine services to go in with a list of what YOU what done, and tell them you'll grease your own door hinges!
I had an XJ6 several years ago & the wife called and said they wanted to do the 15,000 service while it was there for $650. Told her to bring me a list home of what that included - oil change and all the garbage listed above - RIP OFF!!
