Hi I ordered my car through DTD, was also a bit nervous - but a piece of cake. Would do it again no problem. Placed order with DTD then received call from a VW main dealer in Kent, went through order (5 door, pure white, manual, Adaptive chassis control) and that was it. Ordered in May received September.
Not bothered about PP, but had to have ACC as had it in my MK6 GTI and liked it a lot.
The car is awesome and I cant fault it. The parking brake is so easy and all-round a brilliant motor. With the ACC in comfort mode it drives like a car costing twice as much, it's expensive but you can see and feel where the money has gone - it fact it's so good I consider it a bargain.
My bother in law has the new BMW 3 series and I would say the VW is a better car.
