As for buying old cars and rebuilding them, I'm not sure how many cars are left to be purchased. The PE was abandoned in 1961, with most of the cars being scrapped (for instance, there are only two "Tens" left, both at the Orange Empire Railway Museum in Perris). Besides, the more iconic cars such as the "Tens" are really quite large (this type of car was shown in the concept drawings). These would need to be scaled down to look appropriate. The other type of car shown in the concept drawings, known as a "Hollywood" car because it was used extensively on Hollywood Boulevard, while presenting a smaller profile, is still quite large.
