Looks good Ross - sunroof is a nice option. Many other options other than the rear parking sensors?
As you say, the Sat Nav can be retrofitted - exactly what I did with mine. Made a very worthwhile update to the car.
Is yours DSG or manual? I was looking for a manual, and ended up with a DSG - was really surprised by how well it drove!
Either way, bet you can't wait to collect it!
