At the time, I was comparing the cost of owning a car vs using car2go, uber, etc for a few trips a month. In the end, it basically just showed that owning a car wasn't all that expensive, and the convenience was WELL worth it.
My current car is worth ~$5k, and these numbers are actually a fairly good representation of my costs over the past few years. I take it in once a year to get the oil changed, and do other small repairs, but otherwise it just kinda.. works. Parking and other costs from living in a city might swing this calculus a bit more, but at the end of the day, you don't need a brand new car, and a modest 10 year old car can drive well, without costing you very much.
