I think the point here is
I think the point here is that Tesla specifically refers to savings over the cost of gas. The only M-Y that can be ordered right now (at least from the website) is the M-Y dual motor long-range version, and the website states below the listed price: "Costs above include potential incentives and gas savings of $6,800." If Tesla means savings including maintenance costs, then they should state so. Of course, maintenance costs on a Tesla can be very, very high when off warranty. And the do break. It is reasonable to compare Tesla with a gas car, but a hybrid is not an unreasonable comparison. Tesla has a habit of pushing the specs in all categories, and this is just one example.
