How much does it cost to maintain a car?

Give a rough estimate of how much you spend per month, on insurance, car repairs, car accessories? any other costs associated with owning a car that a non-car person wouldn't think about before buying a car.

Basically any costs besides the car price itself.

although to be honest all of above would be influenced by the price of car to begin with, so maybe

give an estimate based on a typical car price, your average/low tier car.
