Yes and yes
I recommend getting a car because they can be fun to drive and will also give you some freedom. But only do so when you have the money. Cars are usually not cheap and you must maintain them to keep them running. There are many different components that need to be maintained (exhaust, transmission, steering, engine, suspension) if any of these fail be prepared to spend a few thousand dollars
Not to mention you will also need to buy gas and get the car registered and have insurance which also costs $$$
