The term "used cars" refers to vehicles that have previously been owned and driven by someone else. These are second-hand or pre-owned automobiles, which can be purchased from a dealership, private seller, or through other means such as auction. Used cars come in various conditions, ranging from nearly new with low mileage to vehicles that have seen significant wear and tear over time. Buying used cars is often more affordable than purchasing brand-new models, but it's important for buyers to carefully inspect the vehicle before making a purchase decision.
