Any suggestions re a car cover to help protect a 2017 LX? It'll be outside for a month this summer while my college student son does military training with the Marines and Navy. The elements won't exactly be harsh in San Diego but I'm looking for advice re a cover that fits well, provides sun protection, has some type of lock or alarm, and any other important features I'm not even aware of. I'm not price-sensitive and am willing to pay up for higher quality. Thanks in advance.
