I have taken the XL size which fits so well, she was just on my car (CLK 200) the first two night shifts were so good no scraping ice no snow no wind !!!!!. On the third day then blew a breeze strength 2 to 3, in other words not much wind. This breeze ranged from but to turn my garage half a steering Dragon. The tarp is actually no longer usable because the gums are completely worn out. So back to the front window cover and Fingerweg of the half garage when they used out there where a little wind can come up with.
