There's a place in Bangor Train station with unmarked cop cars, which rather foolishly says "Police Parking Only" on the bay floor, so if you want to update your knowledge on any umarked ones - pop into the station every so often ha. There's a chaved up Corsa there pretty often - that's an undercover one apparently. And the Focus (GWF) hides in St. James' church opposite Morrisons in Bangor very often - see him when I go to the gym, so watch out lol. See quite a lot of boy racers / chavs / chavettes cutting that mini roundabout... Not calling any of you neither, but dont be tempted. lol
