I have just managed to get an approx £5000 discount from a local dealer on my order for a MK8 Golf R, with the following configuration: Lapiz Blue, Performance Pack, Winter Pack, Discover Nav Pro, Harmon Kardon Sound System, Side Air Bags, DCC, Heads Up Display, Rear View Camera, Extended Service Plan and Paint Protection.
Delivery will be around October/November all going well. I know its still over the £40K price, but you only live once.
As a side note I found Coast 2 Coast gave better deals than DTD and Car Wow. But as a side note 'Evo1986' is also a bit of a legend and gave me a quote which was really tempting.
