Hey guys I have a black nappa leather 2.0 and the back seat has what looks like to be the same grease like looking areas in the back seat when the light hits it. It looks like oil or some kind of something was rubbed on the back seat that is either wax or something. Either grease from the factory rubbed off onto the back seat when put in or our local dealers used something on our seats that they shouldn't have. I have the flu right now of course with my luck so I'll get on this soon. One battle at a time.
