Every used car I test drove recently from several official BMW distributors had the same, pleasant, interior "new car" scent. It isn't leather, because they all had "leatherette", so it must have been some cleaner or interior wax used, either on the seats, carpets, or trimmings. Anyone know what it was ? I've had my car 3 weeks now, and the scent is fading... I'd like to bring it back. Perhaps on the same topic, what does one use to clean "leatherette" - any vinyl cleaner ?.... could I use a leather cleaner ?
