Another explanation, my W201 was originally destined as a special delivery for a dealer in Massachusetts, but the Mercedes dealer in NJ was able to "divert" it. Before delivery, the dealer removed the orthopedic seats that were in it and replaced it with the standard driver's seat. The orthopedic seat shows up on the window sticker, but on the bill of sale, there's a credit for the swap. So, it could be that the dealer did the change out for a customer or on their own.
