<human>:  I'm planning to buy a car. What are the things I need to think about before signing a contract?
<bot>: Before signing a contract to buy a car, it is important to consider the price, fuel efficiency, insurance costs, repair and maintenance costs, any additional features or benefits, safety ratings, and the car's resale value. It is also important to check the car's history, including whether it has been involved in any accidents. Finally, make sure to read the car contract carefully to ensure that all the details are correct.
