My '65 F-85 Deluxe has the original front rubber floor mats (with Oldsmobile stamped into them)still in it. I was just curious if it's supposed to also have rear floor mats as my car doesn't have them.

 

"Auxiliary Floor Mats" were a high-profit extra cost option back then. You could order B32 front alone, B33 rear alone, or both together. They were color keyed to the car interior.

Fronts have OLDSMOBILE molded into them. The rears have the same pattern as the flat floor part of the fronts.

Repros are available, but in black only.
