Used cars are pre-owned vehicles that have had one or more previous owners. They are typically sold at a lower price than new cars, making them an attractive option for budget-conscious buyers. Used cars can vary widely in age, condition, and mileage, and they may come from dealerships or private sellers. When purchasing a used car, it's important to consider factors such as the vehicle's history, maintenance records, and any potential issues. Many buyers choose to have a mechanic inspect the car before making a purchase. Additionally, resources like Carfax or AutoCheck can provide valuable information about a car's past.
