Many parts of Cumbria use modest spec silver Skoda estates. The usual giveaway is a total lack of dealer or other window stickers, Magic ~Trees??? or anything else civilians might carry in thier car.
In other words plain cars are just too plain!!!! 
Look for the extra 'bump' on the top of the passenger mirror. Not allowed to have interior passenger rear view mirrors these days... 
Bit difficult to see some times H21 but why no interior rear views :-?
For the same reason why air fresheners from the interior mirror cause it to fail an MOT - it obstructs the drivers view of the road ahead.... 
Amazing all those years the boys in blue were driving round so dangerously, it must have caused millions of accidents too.
Another one for the H&S bollix file methinks.
Agreed, to an extent. It did get a bit bulky for a while with two full size rear view mirrors and a chunky 1980/90 style video camera hanging from the roof. There was a fair old potential blind spot that you had to work around...
See what you mean but surely at the top of the screen it's a less used area, unless you spent all day chasing the force helicopter.
I have been searching google images for something suitable but nowt available yet.
Imagine the standard mirror fitment for the driver.
Then add a same size mirror for the observer attatched and hanging directly beneath and pointing in completely the wrong direction.
Then a 80's/90's Hi8 camera hanging beneath that again. Your available screen in the centre is getting distinctly crowded, Cap'n...
