Is this legal ?

It is legal to sale. The catch is what you do with it when you have it and that is different as to where you live. Think about the camaro and mustang people that buy the "new" 1968 cars made from new body suppliers. They buy a rust bucket with good paperwork just for the numbers. In fact the state of Georgia do not require titles on older cars.

If not many of the new super slick camaros would be show or track only.
