Is NavPro good looking? YES!
Is NavPro more useful? YES!
Is NavPro worth £1350? Hmmmmm
But you can say that about any of the options... bigger wheels...paint...seats...lane assist...
I personally don't think 19's do anything for me... I'd buy them as a 100 quid upgrade, but not what VW want.
I liked another colour (I have white) but couldn't justify money for a colour (hell, I'd have not paid for white but that purple was soooooo bad)
The thing with all of these extras are VW trying to edge more money out of you for not a lot of extra functionality - it doesn't drive better, it doesn't go faster.... its just bling. If anything VW UK's packaging of the performance golfs with loads of "free base spec" is actually upselling in the first place. They know that most people wouldn't spec to £28k if they offered a basic GTI without the toys (like in Germany) at £19k. Thats 9k of extra money they'd never see...
