I recently purchased this house and it has a massive two car garage. I could probably actually fit four cars in it if I was very careful. It's empty aside from some of my moving boxes and a work bench.
You are welcome to use the space for storage, as a workshop, or whatever. You will need to coordinate with me to have access to the space, but I am pretty flexible and almost always home. The house and garage have 4 security cameras and other security features.
