THE OLD BLACK FIREBIRD was blocking our exit from the gas station. As the passenger door opened, I saw the look on the face of the immense, camouflage-clad good ol' boy who sprang out like he'd just spotted a new form of game on his personal hunting grounds. Throwing the Cadillac ATS-V coupe into neutral, I jumped out to greet the man before he reached our group. I spotted a sun-worn but freshly polished badge on the Pontiac's front fender. No way. Could it be?"Eighty-eight GTA, am I right?"(NAIAS) Detroit Auto Show
