From the web, not original, but I can see why you'd like more information! I guess they intended to rule the freeway with an iron fist in 67. 4 speed even. Wonder if it was all F41 as well?

Cool news clip. It seems like something must have appeared in TV or films. It seems like I recall seeing something with either 67's or 68's but I cannot recall what it is I'm thinking of and if it was even NY.
I wanted to see if there were search images and something turned-up. Where else but on CT! This thread isn't specific to NY and some of the photos no longer appear due to the dreaded photobucket debacle but it still likely has some interesting information which likely applies to the NYS cars as well: https://www.chevytalk.org/fusionbb/showtopic.php?t...
The last time an update was posted was 2015. I think police car or not a 4 door Biscayne would be a cool car. A lot of cars, not just Impalas, which were not 2 door and "nothing special" have disappeared so it's always cool to see something like that.
