I've had 9 Pontiacs in my lifetime, the fastest was a 1970 Firebird Formula 400 Ram Air V, yeah that tunnel-port, aluminum-head, super duty, 12:5-1 compression monster that cranked out 500 HP. Had the turbo-hydro 3-speed auto and 3:70.1 rear axle...Very fast car that was mostly stock in appearance.
I know have a pristine 99 Bonneville SE that is factory fresh.
I'm a fan of the Catalina 2+2 421 tri-power HO cars..
GM made a grave mistake dropping the Pontiac line.
