Highline also gives you Satnav information (when used in conjunction with MFD2 radio).
Directions, road name, time to arrive, distance to go etc.
Whilst you may have not gone for the satnav on day 1, I didn't order it either but got one off ebay cheap and it's an easy fit. If you get the highline now at least you have the option later.
Highline = best value for money.
I love the xenons, but it is a bit of a luxury and hard to justify value wise.
The DSG is an awsome option, but so is the price tag, did u get chance to test drive a dsg?
I went with the sunroof but you have to open the window at the same time or it plays havoc with the wind noise. That is the 1 extra I could have done without.
My philosphy was F*@k it stretch myself cash wise and not regret getting the toys that would be too difficult to fit post manufacture.
