<human>:  What is the best time to buy a used car?
<bot>: The best time to buy a used car is usually in the late summer or early fall, when new models are being released and dealers are looking to make room for the new inventory. This is when you can often find deals on used cars since dealers have the most to gain by selling them quickly. In addition, you can use this time to research different models and find the best possible deal.
