My dad used to have one of the unexpectedly rapid executive-model Cavaliers... How he loved to make boy racers look daft. He was quite cunning though, he'd make sure he didn't accidentally race an RS2000 or a hot GTi, just the wee rubbish ones
My favourite though, was a wee Saxo or somesuch that decided he wanted a race. I just rode normally, while he was wheelspinning off the lights... Overtook him after a moment, carried on, stopped at a set of roadworks up the road. He pulls up and shouts "That was fast mate, but I nearly had you!" "Sorry, were we racing?"
