Maybe someone can inquire about the VIN and verify the stamps. Looks like 7N22220X.
I have never seen one stamped like that before. MQ MR
MR = Owners initials.?.
MR for smog. MQ no smog.

Yeah I realize that. Just giving a possible reason besides the obvious.
7N222201, was for sale before.
Stamp looks OK, IMO.
