I was going South on the Tpk Thur afternoon about 5:30 between Boynton Beach and Atlantic and had a GN go by me. Only distinguishing feature was black GNX honeycomb wheels (no center caps?). Anyone on here own it? He was moving a bit over the speed limit and after he went by, a new blue GT500 Mustang went sailing by trying to catch him. BUT there was a cop in the way otherwise it would have been fun to watch.
