I heard a story of a young lad that got pulled by the old bill for speeding they run the number plate on their system came back as 1.2 corsa, copper realising that a 1.2 corsa wouldn't ever be that fast asked driver to open bonnet to reveal a 2.0l red top. Car insured as 1.2 car was seized by police and destroyed as he technically had no insurance. Now i'm not sure if this is an urban tale or not.
