To present a valid comparison, you must include gasoline costs and insurance for your fossil-fuel burning, earth-destroying, murder-machine, since you are tossing in "75-90 for an unlimited plan," to be fair. You cannot drive a car without gasoline and insurance.
Also financing a car and financing a phone are not the same. You are buying the phone with "financing;" the phone company is just giving you 2 years of 0 percent interest. When leasing a car, you are renting the use of something which isn't yours and has ro be returned at the end. So your comparison totally fails on all levels, even if it was true that a Honda Civic could be rented for $145/month (no idea if this is true.)
Better suggestion: if you lived somewhere desirable, and with public transportation, you wouldn't have to waste half your life driving a honda Civic to and fro, poisoning the earth, filling your tank with gasoline, buying car insurance, and leasing automobiles, and you could instead purchase desirable products like the iPhone X.
Also, if you have friends or a family, you need not pay $90/month for cellular service. The price of cellular service is also irrelevant to a discussion of the Phone. Presumably you were not just going to go without cellular service if you didn't buy the Iphone X, amirite? Right.
