<human>:  I want to buy my first car. What should I know?
<bot>: You should start by researching various car models to find one that meets your needs best. Consider factors such as the type of driving you'll be doing, the size of vehicle you require, and your budget. Once you have an idea of what you're looking for, you should read reviews and ratings to get an understanding of how reliable and fuel efficient the car is. If you can, it is always best to take the car for a test drive before you make a purchase. You should also compare prices from different dealers and explore different financing options. Finally, look into getting an extended warranty, if available, to protect your purchase.
