I took a cover off and looked at what looked like the sump plug, a small bolt with a leather washer looking brand new. I do not believe the car has ever been drained from there, there are no oil smudges to be seen, it looks 100% new. So since I was not sure if that was indeed the oil drain plug I did not touch it (it could be the auto-gearbox drain or final drive drain or god knows what).
