"13,000 reservations in Q3 for estimated order book of greater than $1.3B."
If it was 8000 reservations for $700M in sales in February, that means that the incremental reservations of 5,000 reservations through end of Q3 represent $600M in sales for an average of $120K per sale. This would suggest that sales are skewing heavily toward Grand Tourings at the expense of Tourings and especially Pures.
If you use the estimate from June of 10,000 reservations and $900M in orders, this means that from June to September, 3000 reservations and $400M in sales have been added at an average transaction of $133K per sale. This means that the overwhelming number of new reservations (at least 2500 of 3000) added during this time must have been Grand Tourings. Which means it might be a while before I see my car.
