Nice find! This one is nice but 87 GNX looks better, with black rims and chrome lips, enlarged fenders.. 547 Buick GNX were made in 1987... These days, true GNX can be sold for more than 50,000$.. One guy near my house have a speed shop specialized in GN.. The owner have a 750hp Grand National... when he pass on the street, i know it's him by the sound...
