Your chart kinda sucks, is it supposed to be a percentage of 30k? Or is the vehicle itself 30k and then you pay more for fuel, but then wtf does 28% fuel mean!?
There's also parking which can be expensive. Cars suck, if I had a lot more money I would probably have one for weekends but thankfully I live in a bigger city and i have ways to get around to about 90% of events that I want to and I have to rent a car once every few months or ride-share.
