Yeah, got to keep your expenses minimum to make any money, and you CAN make money if you do that.
But a part-timer who needs a regular car for regular uses and a full-timer have different needs. If you are driving Uber full time you are probably not the best candidate to own a new car at all. Being I like to own 2 cars anyway I have my regular car that I don't drive for Uber and a cheap minivan which I do, and that's also my second car. If you want to be a full-time driver and you drive a lot other than Uber you might want to consider buying two used vehicles, one for Uber exclusively, and another for personal use that is acceptable for Uber that you can drive when the other one is not available so your income isn't interrupted. You can buy 5 used cars for the price of a new one.
