1972 Pontiac Grand Prix 455 test drive
1972 Pontiac Grand Prix 455 test drive and inspection. I've said it before and I'll say it again: there is no replacement for displacement. In this case, 455 cubic inches of displacement. Although this car was in its today considered to be mid-sized, it nearly dwarfs everything today. Not to worry though, its got plenty of power and is definitely one of the nicer surviving Grand Prix's around today.
