i have traded the wife for a more pro-corvette model, happy days
I did similar too. Ex-wife and I split up, and one of the first things I did was look around for some old cars to play with. Collected a few, including my 1968 Corvette. Love it to bits. Then I met my now current wife shortly after buying the C3, and she loves it to the point that whenever I suggest selling it she tells me never to sell it and would probably ditch me first before the car LOL.
Anyway, as to the C3 and dry storage - I used to have a lovely garage at MY house before meeting my new wife. I moved in with her, and there wasn't a garage available there. So I contacted the local council and asked about any of their garages that might be available to rent. They did have some. Granted its about 1/2 a mile from the house, and the garage is so tiny that the C3 takes up all the room, and I had to "modify" the garage door opening area as it was a few CMs smaller than the C3's width. But hey, its a garage, it stays dry and out of the watchful eyes of everyone else. Much better than outdoor car covers as they always leak and blow around in the wind. I used one on the C3 for a bit, but its not great.
