Victor, we have the description of the section as "original or mostly original". We don't have a strict guideline at this point. In my mind the car should as a minimum have the complete original engine, trans, rear axle. Original or mostly original paint and interior. If the car has had some very minor paint repair or a seat fixed, it may still be considered.
But those are kinda what we are looking for in this section. Unrestored...
We will see how this evolves.
