So Craigw orders his 5 weeks after me from same dealership, ( mine in Merylee) and his is in transit, and mine won't be built for a fortnight .
Strange allocation system.
Perhaps you'd like to lend me yours till mine arrives in September. 
Speaking
hypothetically... I wonder how VW would react if someone were to make a complaint about this? I suspect they'd just fob it off with excuses about different spec, but what they should really do is properly look into why some orders take so much longer than others which seem to 'skip the queue'. Perhaps there is an innocent explanation, but perhaps they need to make some changes.
It wouldn't be so bad if they could actually provide roughly accurate estimates for delivery, but because they had us all expecting delivery around early August and then changed this to "delay of unknown length" with some cars coming through much earlier than others they've angered a lot of people.
I think we'd all be a bit less pissed off if we'd known what we were getting when we signed the deal. And that means either telling us straight that "some cars will be build fast, others will take months longer with no fixed date and its near enough random which your order might turn out to be" or to get their system working so they can provide a decent estimate.
And its not enough for them to cop out by saying "can take anything up to 20 weeks" (and for some of us its well over that anyway) because that would still cause irritation when some come in 10 weeks and others in 20 weeks. The estimate needs to be accurate or they need to be honest about how absurdly random the lead times really are. Feels like mis-selling to me.
