As ideal as it sounds to have a sponsor throw money at a historic class to get the cars on the track together, unfortunately its really not a reality. Historic racing the world over is the same, at the end of the day it comes down to each car owner putting their hand in their pocket and funding the racing themselves. The best you can hope for is that enthusiasts will put in the time and effort to assemble of grid of similar cars, and make it as easy as possible for car owners to come together to produce an interesting show for the punters which is what we've seen with various classes around the world.
