Hi, they are trying to rip you off for a start although they try and fob you off by saying the car HAS TO BE DONE by the dealers (Take no notice) there are a lot of small VAT REg garages that will do the job providing they use the genuine parts for the car inturn that will hold your warrantee, check around your area for a family run garage ask for a quote in writing then take it from there, A lot of peole are under the impression that the car has to be serviced by the dealer I understand before it is said a Ford Mech to a Ford Etc but I like everyone else knows when they are getting ripped off as you have said.
