Grand Nationals were THE car of the 80s. A lot of guys bought them and put them away as investments and I don't think Ive ever seen a GNX that had any miles on it. "Base" Grand Nationals seem to be either well-preserved low-mileage originals or were run hard, roached out and need a resto. Mine is one of the roached out ones that I brought back to life and is now one of my drivers.
