Yeah, IMO unmarked cars should NEVER be allowed to be used for traffic enforcement. That's BS. I believe some states have regulations against that practice. When the 5.0's came out they might as well have been unmarked because it took everyone a while to get used to seeing them.at 17, my uncle and i drove his brand new '89 stang 5.0 from IA to CO and saw all the NE state patrols driving the same car. plenty of unmarked camaros/stangs around here too. great we pay extra tax $ so they can create sneaky vehicles to fck us.
