Ok coffee aside here is what we know.
That license plate style was used in Virginia from 1979 to 1992 but they got to Z plates at the end, so starting with a Y would be a 1991 registration by the last Virginia owner, the civil servant. He (because we said it is male) renewed the registration until 2002 as shown by the sticker, at that point it went Nonop, yet kept garaged. The manual front windows was a deliberate preference I would make any day, lighter and does not break like the electric. This is confirmed by the choice of leather, it was not about cost. And we know it has leather interior because German vinyl lasts forever so they car would not have seat covers unless it had leather and naturally is in bad shape. Few people know that while sun is bad for leather, very cold either is even worse. I postulate the new owner is actually blood related to the civil servant and is the new caretaker of the car, and possibly lives in Atlanta.
Only a carefree young person would drive to Atlanta with license plates that expired eight years before. The new owner knows little about classic BMWs, otherwise he would have asked our experts before starting rejuvenating the car. The missing grills are in some box in Virginia. The black decal behind the missing side grill looks original and intact, therefore I concluded it is original paint, or a 1990s repaint when body shops still knew that part was needed behind the grill. The new caretaker has and will not find us, because he is young and is probably in Instagram, not on our last century (and proud of it) media.
