I've never seen any of those. In speaking with people from different law enforcement agencies, most, if not all, undercover vehicles down here are as I described.

Many unmarked cars here are colored Chevy Impalas (dark green, blue, etc). VA State Police have some pretty nice Camaros, but I think there are only like 4 in the entire state. Military Police around here have started driving marked white Impalas. There are still the old Crown Vics and whatnot, too.

some of the dallas areas now have new dark blue and black Impalas that have NO markings at all except small lights in the front grill. We also have a few camaros. For those of you who don't live in Texas, we have TABC-Texas Alcoholic Beverage Commision, which monitors alcohol sales/service in dry areas, who also have barely marked black Crown Victorias-I have been followed home by one before after purchesing beer from a convienence store-they asked to see my I.D,then left. Freaked me out.

Don'cha love how totally F'ed up DFW Metroplex liquor laws are? Ya practically need a MAPSCO (the local publisher of street atlases) to figger out where to buy booze in this town! I've been living off and on in the DFW area for over 10 years and I think I've finally gotten the hang of where the wet, 'moist' (beer and wine only retail sales, hard stuff in restaurants only) and dry areas are!

I've always been told that if you think you're being pulled over and there's anything suspicious about it (such as it being an unmarked car) you should call 911 and ask if you are being pulled over. If they say yes, you go to a well-lighted, well-populated area and stop. If they say no, you don't stop, and they should dispatch the real police.

A relative of mine was nearly a victim in a not-too-dissimilar situation. A guy had gotten hold of a police uniform and would offer young ladies a lift home, then he'd take off with them and rape them. My relative escaped only because she noticed he was wearing argyle socks, which are not part of the uniform, and jumped out of his moving car.

In SC, I've seen Camaro's, Durango's, and I've even seen a BMW (what was that about?) as undercover or HP vehicles. Some of them were marked, but when you are on the highway and they are behind you, you can't tell.

Arkansas was famous for an "unmarked police rapist" a few years ago. Scary stuff...he apparently would seek out the country roads with nothing around for miles and miles.

I know we can dial 911 from our cell phones...I think we can also dial a different number to get Highway police (on the interstates).

Our police have different types of unmarked cars...Camaros, Impalas, etc. They also have started marking the car on only the right side so that they can sit on the side of the road, tag people for speeding, but you think it's just a regular car until they show you the right side of the vehicle.

The police also mark and use a lot of cars they confiscate during crimes and drug deals. I've seen a State Police Ferrari running around here...looks interesting.

Yeah, you basically have to carry a zillion forms of i.d. with you, and drive to the middle of no where to get booze!! and they all close at different times. Such a pain. Someones post earlier reminded me I have seen a Dallas P.D. viper once cruising down the highway. That was bizzare. Black with blue markings. Odd.
