Hi Horace, As you suggest, I could have just ordered the same part number and presumably, gotten the same fit. Color was not a deciding factor, I just liked the Anthracite , especially since the dimensions of both colors is listed as the same. After receiving my cover, I wrote asking specifically about dimensional differences between yours and mine, listing the two part numbers. I also asked if this could be a quality control issue and sent them a copy of the Europa dimensions and pictures listed in the manual.
I was disappointed in their response. They weren't interested in addressing any of my questions. My top priorities were material, fit and price. Except for the fit, the cover is good.
Glad for you since the fit looks to be quite good and you avoided the cross Atlantic shipping fee.
