The cheapest car to buy isn't always the cheapest car to own. Fuel economy, routine maintenance, tire replacement, repairs and depreciation all add to what you spend over the years you keep a vehicle.

Look up the estimated fuel economy of each car you're considering and think about how much you drive. A vehicle that uses more fuel can quietly cost a lot more over time, especially with a long commute. If you're weighing a hybrid or electric model, consider charging access at home and work, along with how electricity and fuel prices compare where you live.

Research typical maintenance needs and common repairs for each model. Some vehicles require pricier parts, specialty tires or premium fuel, while others have a reputation for running reliably for many years with basic care. Owner forums and reliability reviews can offer clues. Weighing these ongoing costs alongside the purchase price can help you choose a car that fits your budget for the long haul.
