Well if the car works reliably, and is not a death trap that will kill you, then obviously the answer is "yes" because owning a car gives you the freedom to travel anywhere that has roads on your continent.
If you don't have a car, then your freedom to travel is significantly limited versus having a car.
Personally I've been a car owner for about 30 years, and I would never consider not owning one again. I've had lots of trouble with cars, spent lots of money on them, but it was all worth it to have the freedom to travel.
A used car that works can be a great investment. It can also be a money pit if you get a lemon though, so get somebody to check it out first.
