just coming out of woking in surrey - drove round a white van pulled on the side of the road and at the front was a SAAB 93 Aero in black maybe 54 plate ? with blue lights in the back window flashing - cheeky buggers, looked like the back windows where tinted as well - in no way did this look anything like a plain clothes car that they use - looked a bit dirty/dusty just to pass in the crowed
so be careful if you having fun that way
