The 116 and 124 dont get driven much and sleep inside a sealed garage. This doesnt stop dust, children and other stuff dirtying them. I had used external covers I had lying around but they looks messy and they are quite harsh, possibly scratching the cars when put on an off. So I saw these at Autobarn here in Australia. SAAS brand. An XL for the 116 SEL, and a L for the 124. They are very soft and I think reasonable for their intended role
