i emailed about this last week. as you can imagine for people who have still not had a build date and then seeing this.
the reply i got
Karl,
I am afraid that you have highlighted a glitch on our online ordering system as I can confirm that we definitely do not have any GTs available in stock in any colour. We will get the website corrected, but rest assured our Distribution team is monitoring our GT orders and build incredibly closely and if there is any opportunity to get a vehicle to you sooner we will definitely make you aware. It is definitely not advisable to cancel your order and reorder as this would unfortunately move you to the back of a sizeable queue!
