After much deliberation over spec and colour, I placed my order today. I'm expecting delivery around April - seems a long time to wait!
The spec I have gone for is:
Interior Lighting Pack
B&O Advanced Sound system
Fine Nappa Leather seats
Heated Front seats
Audi Parking System Plus
Electric lumbar support
Aluminium roof rails
Through load facility
Rear side airbags
Electric heated/folding/dimming mirrors
Extended mono.pur Interior finish
I think that's everything - can't wait for the spring, does anyone have a time machine???
I'd like to thank everyone who has helped me decide on the spec, colour, etc, especially Vertigo1 (Toby) who met me on a very rainy day and blew me away with his B&O audio!
