Human: How can I make sure that I'm buying a safe car? Assistant: 
To ensure you are purchasing a safe car, it is important to do your research. Check the safety ratings of different models and read reviews from other customers who have bought the same model. Additionally, consider looking into the vehicle's crash test rating, as this will provide an indication of how well it has been designed to protect its occupants in a collision. Finally, take the time to inspect the car before purchase to ensure it is in good condition.
