Just got back from the dealer and placing my order.
Quite a few changes from my original spec based on feedback from you all and from reading other threads.
In the end I went for:-
5 Door DSG
Carbon Grey Metallic
Standard 18" Austin Wheels
Standard Seats/Tartan
DNS Discover Pro
Dynaudio
Performance Pack
High Beam Assist
Adaptive Chassis Control
Park Assist
Rear View Camera
Winter Pack
5 Year Extended Warranty
Service Pack
Drove an EOS Diesel DSG and really liked the gearbox, hence why opting for it in the GTi. As I'll be doing a mixture of long (business) and short (personal) trips it made sense for the comfort/ease.
I kept the park assist and high beam simple because I like toys! Doubt they'll get used much at all but nice to have.
After reading feedback throughout the forum I kept the Tartan seats, on review they are really good seats. I also love how the red is carried through the cabin.
Managed to secure a discount of around 8.3% - Around £2800 off list (including options). Fairly pleased with that!! Dealer even said that they've had no-one who's negotiated that much of the new GTi.
Now the long wait, deal estimated October but likely nearer Christmas based on other feedback.
