Most of my car (including the seats) is standard-equipment spec. for the TT.
Had another 125mi ride today, and the one thing that strikes me the most is the grip. I kept looking for the bumpiest, nastiest tightening-radius turns to push harder through, and I just can't ruffle the chassis. I entered on- and off-ramps at speeds my brain was screaming "way too hot for this turn! slow down!" then proceeded to accelerate through them.
Cool stuff.
