Not really, it's a silly question. Can you leave a mass-produced Japanese built car outside without any problems? Well of course you can!
If the question had been "Is there any benefits of covers/garaging?", then that would've been perfectly reasonable. I'm not trying to be harsh, and I mean it with the greatest of respect to the OP, but this isn't the 1970s anymore. Garaging is awesome, my car lives in there, but I also don't fret when parking it outside for a long period of time. Covers I would never use, for the risk of scratching is too great unless it gets a 100% clean before you put it on. Probably okay if you have the time and/or don't drive the car very often, but it's not for me.
