The pics look real good mate.
I am waiting for my Mk5 GTi like a kid at Christmas. It was due 9th May, now the dealer says he'll ring me on the 9th with a defo date. I hope he's not putting me off for a significant delay like it sounds like happened with you.
I love the silver, but I've gone for red, cos I'm trading a silver V6 4Motion in and wanted a real change. I must admit i'm a bit worried about shine and stonechips with the red, cos my silver V6 has worn really well, but I couldn't resist red when VW used it in all the brochures and for the press cars.
I agree with your options. I think 18s and leather are a must and have gone for them myself !!
It's good to hear that you are enjoying the car, have you got any grumbles with it at all ?
