Having just bought a GTI VR6 I have to partially agree with Gambit. I read both the Subaru and GTI review and:
The subaru does inspire more confidence in stock form than my GTI. I don't know that I would call it tipsy as the body roll isnt outrageous but it certainly is noticeable.
This may sound crazy but I think part of the feeling with the GTI may be due to the seating. You sit very high and this tends to accentuate what body roll the car does have.
On the plus side for my car it is incredibly comfortable and VERY fast.
