We regret to inform you that there are five 180s in US registry older (by serial number) than your #13 even though that may be your "lucky" number. PA-1 is registered to John Codman (N2024P) in MA. Owned since 1978. Closest to yours is PA-14 owned by Rolland Andrews (N5011P) in Ohio also since 1978.
"Still flying" is an unanswerable question as would be those 180s in foreign registry. There are 726 180s in US registry.
