I know just what you mean. The undercovers in my town have 2 cars that everyone knows, and they both have to wear their uniforms when they're in the car anyway.
lol, same in my town. 2 undercovers, both drive white impalas with black wheels and a spot light on the dash. its so obvious when you see one.
All the UC cops that drive around here are either in Crown Vicks, or those Mercurys. It's funny because you can always tell who they are because they have huge ass CB antennas.
When i first moved to bend there was a uc who drove a white mustang. like an 03 i think. but i dont ever see him anymore.
