People don't realize how cheap it is to keep a vehicle maintained if you don't use it much at all.
And though insurance is officially "tied to the car" it's really tied to the driver; you can't drive more than one car at a time anyway so the third, fourth, tenth vehicle adds less and less.
When I owned two vehicles as a single person it wasn't that cheap to own my two seater car. It was at least a few hundred in insurance, registration, state inspection, some age-related maintenance. I eventually got rid of it for that reason.
