Great to see Mav, we agree on most things.
We agree that Sensis Maps are rubbish: Out of date, inaccurate or just wrong. It matters not how TomTom get a better map than VW (or BMW, Merc, Lexus etc). Here in Oz, they do. Fact!
We agree that the VW Golf is worth a premium over other similar cars. Of course, how you rate a car depends on what you do with it and what you value. IMO, paying $10k more for a GTI that costs VW less to make than a 118 Comfortline is not good value, but for you and many others reading this, the trim, the wheels, the look and especially the performance are worth it. As you said, in your opinion the GTI is great value and I wouldn't dream of trying to persuade you to change the value you put on those things. Just remember though, value judgements are just that. They are relative and full of emotion and no persons values or emotions are worth less than anyone elses.
As I say, we agree that people will pay a premium for what they perceive is a better package. The VW RNS510 is part of what makes the Golf a better package and to scurup I would say yes, it is certainly worth the extra.
