That's bloody rubbish.
What's the difference, in this case, between a classic car and someone blowing up the engine in a six month old Porsche.They wouldn't dare say that guy couldn't replace his engine incase it was a stolen unit,something that would be far more likely to be the case.
They just regard classic car owners as a pain in the a*s*,if all went as they would like,they'd then be marching on parliament because Mr.Cameron had cut their jobs because there was not enough work to go around.
As Martin said,don't tell them,i never have.
Unrelated Question...What is more harmful to the enviroment,running a classic car for daily use or building a whole new car??
