Just clarify: My comment below about the cockpit cover was refering to the cover supplied to me by MB with the part number mentioned in the earlier post...that the MB cover fits both 107 and 113 is correct but...
Hauser is also correct. When I looked again, I see that the cover shown in the ebay link is not the MB cover...as Hauser notes, it has no mirror tie-downs, and no MB logo which indicates that it was not "licensed" by MB to carry the Tri-Star symbol. The ebay cover has some printing on its front center that I could not read.
I have no knowledge about the ebay cover. I heard informally that the MB "official" cover with the logo and mirror tie-downs was made for MB by California Car Cover which sold a cover similar to the MB "official" cover without the logo.
My advice would be to order the cover from MB since it's only about $50 and you know it will fit...plus you get the mirror tie-downs which help anchor the cover correctly and your chest will swell with pride when people see the MB Tri-Star fluttering in the breeze.
