I would add, if your city permits it, buy a bicycle, or take public transport. You can have a car too, but every single trip you don't do in it is money saved. Kids are calling this "low car", in contrast to no car. Car dependence sneaks up on you, one moment you're a teenager with no costs the next you've got thousands a year in running costs and you're wondering where all your money is going. Fuel costs become non-negotiable, and maintenance is both hidden and a Russian roulette as to whether or not something major breaks.
Every time you don't drive the car, you play the maintenance slot machine one less time, and the accumulated effect of lower maintenance costs and lower gas is non-trivial.
The other thing I would add is to be honest with yourself, add up the car costs, rego, gas, tires, the maintenance schedule (you have a schedule even if you don't follow it). Your $20,000 dollar car probably costing you thousands a year.
