Looking at both the 2.5L Golf and the 2010 GTI. I like the amenities of the GTI (turbo, touch screen radio, 6cd changer, fog lights...etc). However, even the dealer told me it was overpriced. The Golf interior seems a little dated in terms of sound/music/bluetooth...etc. Also, the Golf can't add navigation or CD changer (dealer tried and it didn't work). Should I stick with the Golf or spend the extra money on the GTI??
