Just took delivery on my new 85D with gray NextGen seats. Drove it to a friend's house last night and she said that her new beemer leather seats were becoming stained from her jeans and such. In all my other cars I've gotten high end sheep skins, so I am unfamiliar with just how delicate the leather might be. They are SO GORGEOUS that I don't want to ruin them. Anyone have problems with that sort of thing? Thoughts? I'm clean and easy on my cars, but don't know how sensitive they might be. Also, has anyone else done high end sheeps over NextGen yet?
