Used car sales involve the buying and selling of pre-owned vehicles. These transactions can take place at dealerships, online platforms, or through private sales. Buyers often seek used cars for their affordability compared to new models, while sellers may want to upgrade or simply sell their current vehicle. Dealerships typically offer a range of makes and models, often providing warranties and financing options. Private sales can be more straightforward but may lack the protections offered by dealerships. It's essential for buyers to research the vehicle's history, including any past accidents or repairs, to ensure a wise purchase.
