Pennsylvania has always been 25, driven to shows, club events, parades, and one day a week for pleasure, must have another regular car. No mileage limit, no inspection ever and plates are permanent. Must have sealed beam headlights to drive at night. OWNER must sign it is restored to or maintained in original condition, no pictures. We have YOM plates too. You buy an antique plate first , then can replace with YOM for another $75. This is the least invasive laws we have ever had. No one knows that all the hotrod Model A's with YOM plates are illegal as they are not original. Several years ago I had a '29 DB with original paint refused because it was not shiny, back in the old picture days.
