So as the law stands now anyone, without any mechanical knowledge, like me, could decide to buy a jaguar engine and fit it into a vehicle like Lulu, which is not designed for speed, take it for a spin at 100 mph, lose control, crash into some poor driver coming the other way and kill all the occupants of the other vehicle, children included. I understand that most of the members of this forum would never just make them sort of modifications without upgrading the other necessary parts but Commer owners only make up a small percentage of classical owners and I would dare bet that there are some right nutters with very badly modified so called classical vehicles on the road.
