Whats the best way to house a car outside if you've not got access to a garage?

Unfortunately we only have a single garage on the house which is occupied by the old dears car and there aint no way she's gonna shift that for me!

So when I get an RS there's no way i'm leaving it open to the elements even if summer is coming, I wondered if you can still get those 'Carcoon' type things or whats best to use?

Cheers
