I agree up to a point on the lunacy of paying up for options you don't need.
However, VW bring a car out and people queue up to buy, then they add a few options as standard.
Disco Nav is standard now on Gti and not on the R, chances are it soon becomes standard on the R, so those without are lacking.
I know when I bought my GTi which is of an age where Nav was an option, I wouldn't consider one without.
Of course, if you are buying a car for yourself and don't care about future value and residuals etc, then fair enough.
We all have different ideas on how to buy a car.
