Just curious if anyone know what type of leather was used on 2005 C230 Kompressor coupe? I am currently using Lexol conditioner on my seats. Lexol's website mentioned treatment for the more common vegetable and chrome-tanned leather, however, certain leathers are not suitable (e.g. napped leathers, such as suede or glove soft leather, which call for treatment with lighter lubricants.) Please advise?
