I ordered through dtd for first time on Friday 16th April and by the following Friday had been contacted by dtd to run through the spec, then by the dealer (gillingham in Kent about an hour from me) who confirmed it all again (and pointed out the road tax quoted by dtd was wrong which I was expecting), then I got paperwork to sign form them (for gdpr and finance so can get the deposit contribution) then a confirmation letter after deposit taken and an order number (which after pfaffing can see in my vw U.K. as at stage 2)
Only other direct / near direct experience I have is my father ordered a mercedes through them in 2019 but while waiting for build etc merc changed something (withdrew that specific variant for U.K. I think) and he had a choice to start all over agin with a new build date or pick a car already being built to avoid further delay, which he did. I think that was all through that dealer, and it was a fleet one as well.
It didn’t really occur to me - stupid I realise now - to just use the dtd price to haggle with my local dealer (since they would not have to pay a fee to dtd so may still have agreed) or try listers fleet as suggested here.
Apart from all these build week concerns on the vw end it was a lot less hassle than previous dealer interactions I’ve had using dtd. I looked at carwow but wasn’t getting anywhere near the discount
