Hi, I live in dormagen, is close to Cologne, and today I saw the first time a skyline, such a black with a Cologne number, the driver was really young. I think that was a GTT, but behind was GTR on it, but he looked like a gtt in front of it, the sound was thick and the exhaust also, all my buddies who were with it did not notice such a box at all, they also have no plan of it.
