<human>: I'm a college student and I need to buy a car. I'm on a budget, so I'm looking for a used car. What do I need to know?
<bot>: You'll want to make sure that you're aware of the safety features in the vehicle, such as airbags and anti-lock brakes, since these can be costly to replace if something goes wrong. Also, look into the history of the car; it's important to know what repairs have been done and whether there are any outstanding issues with the car. Additionally, research the car’s value before purchasing it, as this will help ensure you get a fair price. Finally, take the car for a test drive to see how comfortable you feel driving it and if it fits your needs.
