Review on Xtrashield Custom Fit Car Cover for BMW M3 320i 328i 330i 335i 340i (2007-2019) – Black Covers 320 328 330 335 340 by Peter Montoya

Car cover provides minimal vehicle protection. Definitely not waterproof and not even waterproof. After taking the cover off for 2 weeks there was a huge layer of dust underneath my black car that had just been washed before it was covered and a few water stains. However, the water stains weren't as noticeable as if I didn't have a suitcase, but they were still there.
