I bought a car capsule from a UK firm called Hamilton. They had one on display at a car show two weeks ago. What makes this item different from "blow-up bubbles" is that you can drive into this as it is like a tent.
Here is their website:
http://www.hamiltonclassic.co.uk/ProductInformation/CairOPort.htmI bought this to use to store my car near the ocean. Air is brought in with a fan and filter and exhausts the air to keep it from becoming stagnant. The filter *may* help reduce the natural salt in the air (Alistair Flack was the rep at Essen and he said it should help but not intended to filter anything other than dust). However, having the car stored in an air conditioned garage within a capsule should provide pretty good protection.
I plan to combine the Cair-o-port capsule with one of those electric anode devices that puts a charge on your car which is suppose to prevent rust. I thought these anode charge devices were a gimmick until I noticed that the propane tank at my house has one to prevent rust.
Attached is a picture of the Cair-o-port.
