yeah we have a few unmarked cars around here that are modded alot. Look like a kids car or something. Both are jet black , dark windows and no stickers whatso ever. one is a 99 Roush Stage 3 Mustang w/500hp and the other is a 98 Camaro Z28 w/450 hp They brought them out in force when street racing got bad around here. You would think people would be able to spot them but they actually blend in very well. Also in the unmarked arsenal here in Charlotte are impalla, crown vic, explorer, excursion, lightning, taurus, focus wagon(i'd be pissed getting pulled by that) Oh when I lived in Germany I saw 96 Porsche 911TT ,BMW M5, MB SL600, MB E55. Autobahn still has cops you know!
