£463 is a complete rip off! If you want to stay with genuine discs/pads these are available for just over £200 from shop4parts (with the 10% discount available on here). The internal cost for these parts within the dealer network is even cheaper, before retail mark-up. So you've paid well over the odds for labour which is scandalous!Been battling with AR Customer Service and dealer since second service in December on this. Result - just paid £463 to get rear discs and pads replaced........now moving onto the Ombudsman.
