<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 should start by researching the different types of cars that fit your needs. Consider factors such as fuel economy, size, cost, safety ratings, etc. Once you have narrowed down the options, compare prices and read reviews from other people who have bought or leased the same model. Make sure to also look at any incentives or rebates offered by the dealership. Lastly, make sure you get all the necessary paperwork ready before going to the dealership.
