<human>:  I'm looking to buy a new car. What should I know before making the purchase?
<bot>: Before making the purchase, you should determine what type of car best suits your needs, set a budget, research financing options, look up safety ratings and reliability ratings of different models, inspect the car you're interested in and take it for a test drive, and consider extended warranties. Additionally, you should consider the cost of insurance, fuel, and maintenance before committing to a car.
