Several years ago, when I was building wooden boats as a hobby, I went to a show and someone had built a "7" style kit car the body of which was entirely made from wood - just like the Austin 7 in the picture. I am sure I must have a picture somewhere....
Nah, everybody should be forced to go through IVA every time they modify a car.
BTW locally there was a furore in one of the local papers because some crusty old Major was forced to remove a huge mascot from the bonnet of his car. Looking at the photo of it it could have decapitated an elephant in an accident.
