I went in to my local dealer on saturday to test drive and place an order, he told me it would be December for delivery, by pure luck he noticed their sister branch had an order for a car to stock with a build first week in September, the status of the order was a code 10 which enabled me to change the spec to exactly what I wanted, fingers crossed now for October delivery.
I got the impression at first that they have no idea of a delivery date of new orders until the factory decided what build week they are allocated, so you have to pay your deposit and wait.
