Thought this may be useful for a few people on here who have AUC or Mondial Insured Warranty (essentially the same thing).
I am due an Ins II in approximately 1k miles and thought i had to get my car serviced at a BMW main dealer this has now been changed to a VAT registered garage (confirmed by phone and through a quick search online).
The best quotes i could get for an Ins II from a main dealer were approximately £750-800 + the brake fluid change.
The best quote i have so far for the above from a specialist is £650 all in or £570 if i bring my own oil.
This might save a few people some cash in the future whilst helping them maintain their warranty.

ETA is there anywhere cheaper than Eurocarparts £63 for 8 litres of oil... http://www.eurocarparts.com/basket.php
