Turning radius sucks major ass. That's my biggest problem with this car. Doing a u-turn on a 4 lane road is almost impossible and turns into a small 3 point turn.
Anyway I have no other problems manuvering the G20. It just takes practice. I once had to back through 2 cars in a driveway with about 5 inches on each side. The side mirrors were practically touching. My g/f was very impressed.
