Got this as a warehouse deal open box. Everything was included -  my guess is previous purchaser just ordered the wrong size. The cover is of decent quality and fits my 2012 mustang GT well enough for the price. I only use it in the garage as a winter dust cover so I can't comment on weather resistance. The included bag, as others have mentioned, is basically worthless (it is so small you can never get the cover back in). I don't really consider that to be a big deal.
