Congratulations. I hope you enjoy it, and you don't have too much longer to wait.
I ordered my GTD in mid Nov, and the dealer was hopeful of an April delivery..........unfortunately not. Earlier this week, the dealer told me my build week is 26, with expected delivery in July. I didn't order DSG, so that's not the reason for my long waiting period - likely to be 8 months from order to delivery, assuming the build week doesn't get pushed back.
