as above the car must be built before 1/1/73 if the car is registered after this an you can prove that it was built before 1/1/73 using the vin number you can then apply for historic tax
i aint a violent person at all but if i see someone doing that to my car i would go out there with a lump of wood an knock the bastard into next week makes me angry seeing this done to your car let alone my own hope you get it fixed
