£312 I would be happy with considering I'd done some ringing around today for my first Inspection One service, the cheapest was £380 at Berry Chiswick BMW and the most was Hexagon of Highgate at £450!
Not sure whether to go ahead with it now, the motor doesn't really need the service until another 8800 miles, just that I thought it would be a good opportunity to give it to the dealer to inspect before the warranty runs out in Jan.
