"Why do you want to work for us?" is an open-ended question. It doesn't demand passion. "I feel like I have a strong existing knowledge of the sort of work that's done here which would make this role a pleasant fit for me," is a perfectly acceptable answer, especially if you're interviewing at a company that manages parking garages. Something about the company culture is also fine. They're not always demanding that you display a deep passion for managing parking garages; it's just an opportunity to explain why you personally would fit into the company/role better than other candidates.
