I don't think you can seriously be suggesting these are equivalent. You would have to go to extraordinary efforts to keep a century old car running since everything will be a custom built part at that point. Some people do it but it is a labor of love (for the car itself or for preserving history). People who do it are fully aware you could buy a new car for one-tenth (at worst) of the cost of a restoration. Houses are the exact opposite. Maintaining houses for centuries is normal, you don't run out of parts and the cost to maintain is a tiny fraction of buying a new one.
