Had the same text as kevincredible above this morning. Just received a call from Tesla to ask confirmation that I can take the car within the two week window 12th-26th August. When I said I'd prefer to delay to the 1st September if possible, the response was that would result in a cancelled order and going back to the end of the queue. Like you I thought they preferred to deliver in the last month of the quarter to have as many registrations as possible in that month for their sales figures, but maybe there as so much cars to deliver to catch up from Q2 they may not care.
