Have used Scotch Mount Extreme on our Honda to mount to a plastic trim piece. We removed the mounted item and the mounting tape after 4 years no marks what so ever. 1) Applied a little heat to the mounted item. 2) Pulled the mounted item back onto itself from one side. (Like opening a door) 3) Rubbed/rolled the mounting tape off both the mounted item and car with a finger tip. 4) Used a little rubbing alcohol to get any remaining residue off the mounted item and the car.
Used the same product to mount a 3m command hook to the inside of the cup holder area on our ID.4 (plastic trim) to hold a trash bag.
Not sure I would use this product on a leather like area without testing in an inconspicuous area first.
