Great thread! For me it is the feeling of solidity and class in every aspect of the car and its performance. But if I had to narrow it down, I think how well the DCC is implemented. It really does give you multiple cars in one. Every other car I have owned has occasionally got on my goat on some days, whether it is ride harshness, wallowing suspension, lack of zip or throttle response. But in the GTI I can tailor the car's attributes to suit my whims, or the conditions. I will say, however, that a pedal box is an essential part of this versatility, as without it the car lacks throttle response and feels unresponsive (to me, at least). Some cars can match, or even better the GTI's performance, some can match the ride, others the refinement. But none have all these attributes in the one package.
