I have the really light tan interior in my GT. Seems to really discolor in spots where my big butt rubs, and any time it goes to the dealership for check ups mechanics dirty pants don't help, its definitely got a little fading to it, anyone recommend any product that wont damage/discolor or dry out the leather? I'm afraid to try anything for fear it will stain it or cause it to suck in the slight discoloring. I also know if I don't do something it will look worse in time. You all seem to know all the tricks!
