Also you can do maintenance/repairs yourself for the cost of parts, self-insure, and, obviously, clean it yourself. For EVs and hybrids, you can provide the fuel yourself (solar). The manufacturer intentionally making things like repairs difficult would be the only reason you "need" to pay for regular services, though that also doesn't really fit into a subscription model either since it's going to depend on how much you've driven.
