How about you cover it with a California Car Cover 'DUSTOP' Cover and then zip it into a CarBag

I used a DUSTOP cover on my old black Camaro and as long as the car is super clean it will not scratch! Just clean, cover, zip and leave it alone and you'll be fine.
Don't forget to deal with your battery and possibly your fuel.
