Why is it that some get their panties in a wad when someone outside the PCS modifies a car, but don't get upset when a combination car is made into an ambulance, or a hearse into a service car by a PCS Member. In both of these instances, these modifications might be reversible, but not any easier than reversing the modifications of the car pictured. At what point does a car loose its historical significance and is no longer eligible for display at a PCS Meet?
