Let's nip this in the bud before it goes any further: John Mozart is not a "car mogul." Just like I am not a baseball card mogul.
Mozart, who I am sure is a perfectly nice guy even if his son did used to get rides to Bullis in what I believe was a Rolls Royce, is a rich developer who collects fancy old cars. Fine, good for him. But please, let's not give his plan to show off those cars any more attention than absolutely necessary. We don't need to be encouraging this sort of behavior.
