Fob mark

hi . just wondering if anyone would know what something means… on the door frame where the sticker is for manufacturer and year of the make of the car, there is an FOB written on it with a green marker … and above the sticker where the latch is that holds the door shut there is an F written on that in green marker… does anyone have any idea what this mark means… thanks for any responses

Buy the car new or used? I’ve seen a lot of new and used cars and this has never appeared on any of them but the only thing I can think of is that it may mean “Freight On Board” and may have been scribbled there by a delivery company for some unexplained reason.

Unless this was a used car and was meant to denote immediate payment upon delivery to the car lot and was the delivery company’s way of coding and making sure the transport driver saw it, I have no idea.

the car was bought used… thanks
