Bit of an unusual post but i thought i would call on your combined wisdom and knowledge

Since owning my RS6 (7+ years), I had the luxury of keeping it dry stored in my company’s basement car park. We’re going to be moving buildings soon (end of Nov) so it looks like I have to look at options if I want to keep it dry stored.
Why dry store you ask……. Well in the 7 years of ownership I’ve only done 14,000 miles (it’s my pride and joy) and as well as being dry stored, its only ever been driven in the dry. The car is like new and I want to try and keep it that way. Also my last RS6, which I only had for 3 days…..was stolen so I’m a bit paranoid on the security front to say the least.
My options are as follows
1. Build car port in driveway
2. Build garage in driveway
3. Get top quality car cover
4. Sell the RS to someone who will actually drive it.
Option 2 may be a long awaited approach as it will require planning permission and option 3 I have reservations regarding scratching and ease of use. Option 4 is the one the wife is opting for but I don’t know if I could bring myself to do it.
I was looking for advice really from you all car ports and your experiences if any. Some do not look all that sturdy and I would preferably like one for the long term (so not a temporary one like a car coon) It will be detached from the house, in the driveway at the bottom of the garden so any info on recommended companies and types of design would be good.
