Thanks. I guess Fastback2013 car is missing the washers then.
The washers or screws with no washers (pan heads) have been a discussion point for years and we find originals both ways so may be a running change but all were chromed to match the rest of the screw heads in the rear panels. On your car it appears that the style of screws someone installed in the latch covers were nor pan head (see first picture and there are washers may have been dispersed around the interior trim panels that may have been moved there when the panels were out and reinstalled at some point in the past.
Its also not unusual that to find owners that added the washers to screws to trim panels (seat backs, rear quarter panel covers for example, to help with enlarged or damaged holes in the trim. But the style of screws that someone put back to hold your latch covers before you purchased the car are not pan head so they need the trim washer.
A much later car with no washers
