I picked mine up (same model as yours) 2 weeks ago. My advice is check the tyres are inflated to the correct preasure. Check for marks and scratches inside and out. Do any warning lights come on and stay on? Make sure the dealer shows you how everything works, particularly Blue & Me and if pos get him to set it up for you. Between 400 and 500 miles you will see the fuel economy drop suddenly by about half for 10 mins. Don't worry, it's just the DPF cleaning itself. You could ask about the eneven tyre wear detailed on this site and ask if they are aware of the problem. If it's something that concerns you ask if they would be prepared to realign to the specs detailed in the tyre wear thread.
And finally enjoy it and the jealous looks you get from every petrol head you pass.
