I think the cars will eventually move into one of two groups, much like the distribution of wealth(think dissolving middle class). Some will move into the concours and collector's group and be mostly perfect in appearance. The rest will be modified to be fun drivers and some may even end life as parts cars.
Mine will be one of the fun drivers that will never be mistaken for a show car.
