slicktop = with flashers somewhere else than the roof??
unmarkeds in holland are:
- tuned Passat W8 (8 cylinder), main camera vehicle for the TV stuff. flashers on teh top of the front window and in the foglight spots
- stock Volvo V70 with T5 engine (most). one magnetic flasher to put on the roof, and 2 in the bumper
- Subaru Impreza (2nd model revision, WRC engine but not the body kit). haven't seen that one with the flashers on
- BMW 7 series from the model year where the headlights aren't completely flush with the front. Used by SWAT team and for high-profile prisoner escort, magnetic flasher when in a hurry, usually motor escort clearing the way for these.
A slicktop is any emergency vehicle where the lights are not on the top of the vehicle. So, yes, what you said is exactly right. Most slicktops you'll see are either detectives, lieutenants, captains, chief/sheriff themself, and traffic vehicles. Nowadays, we like the element of suprise. Washington State has a bunch Volvos, BMW station wagons, older cars - such as 1990's, Buicks, even a freightliner (semi truck). I'm not sure how they are all deployed for sure, but I believe they are for road rage applications.....
