I happened to be following a car yesterday registered thusly:- C 1 1 A V D, the characters spaced apart as per my keyboarding.
Imagine a fixing screw between the 1 & 1 & it reads "CHAVD".
The car was a darkish Mercedes C220 diesel, with no obvious modifications, so the number-plate seemd to be somewhat out-of-place.

( FWIW, this was observed in Essex!)
