When I was getting ripped off at the local Wheel Works in Oakland, one of the managers said a cop car comes by for servicing. One is a NBP 07 Si w/ smoked out headlights. It purportedly has the flashing blue and red lights hidden behind the grill

The other one is TW. Supposedly it roams around the 980 and 580 looking for people street racing.
I dunno if I believe the guy's story, but I'm curious as to what the cars look like. Anybody heard something similar?
