17. The Economics of Car Ownership

The first practical, modern automobile powered by an internal-combustion engine was created by German engineer Karl Benz in 1885 and 1886. His three-wheeled Patent-Motorwagen is widely recognized as the first true car, with a patent applied for on January 29, 1886.

Later, the 1908 Ford Model T, also known as the Tin Lizzy, became widely regarded as the first car to be mass-produced on a moving assembly line. Introduced by Henry Ford, this innovation revolutionized the industry and made automobiles affordable for the average person. More than 15 million Model Ts were sold by 1927.

New light vehicle sales in the United States reached approximately 16.2 million units in 2025, following 15.5 million in 2023 and about 15.9 million in 2024. Based on historical trends and available data, more than 780 million new light-duty vehicles have been sold in the United States since 1970. Over a roughly 100-year span from 1925 to 2025, the total likely exceeds one billion vehicles.

America’s Deep Car Culture

American car culture is deeply ingrained in daily life. More than 90 percent of United States households own a vehicle, treating them as essential symbols of personal freedom, independence, and convenience. Approximately 58 percent of households own more than one car.

The average American drives approximately 13,500 to 14,500 miles per year, or roughly 37 miles per day. Europeans drive significantly less, averaging approximately 7,000 to 9,000 miles per year, largely because of shorter commutes and better public transportation.

The Cost of Owning a Car

Cars are expensive and becoming increasingly more so. As of late 2025 and early 2026, the average transaction price for a new automobile in the United States has hovered around $50,000. Average monthly payments often reach between $750 and $772.

Approximately 60 to 80 percent of Americans finance their vehicles, while about 20 to 40 percent pay in cash. New automobile loans typically fall between 36 and 72 months, though some extend to 84 months. Used car loans often follow similar terms.

Interest rates also matter significantly. For example, a $44,500 loan over 72 months at 4.29 percent results in a monthly payment of about $702. At 6.8 percent, the payment rises to about $754, costing $3,744 more over the life of the loan.

Americans tend to keep new cars for an average of 8.4 years. Meanwhile, the average age of all cars on the road has reached a record 12.6 years.

Smart and Not-So-Smart Ways to Buy

The worst way to buy a car is to walk onto a dealership lot unprepared, fall in love with a particular vehicle, focus only on the monthly payment, and allow the dealer to control the financing, price, trade-in value, and add-ons.

A helpful strategy is to treat the purchase as three separate transactions: the new car, the trade-in, and the financing. Each should be negotiated separately.

From a purely financial perspective, the most cost-effective approach is often to purchase a low-mileage used vehicle, ideally three to five years old, pay cash, and drive it for many years. This approach avoids rapid depreciation and interest costs.

However, new vehicles offer advantages such as manufacturer warranties, advanced safety technology, improved fuel efficiency, and modern features. For many buyers, these benefits provide peace of mind.

Timing and Depreciation

The best time to buy a new car is typically during the final months of the year, especially December between Christmas and New Year’s Eve. Dealers are often motivated to reduce inventory before year-end tax assessments.

Vehicle depreciation is also important to consider. Cars commonly lose 20 to 30 percent of their value in the first year and roughly 60 percent after five years. Trucks, sport utility vehicles, and certain brands such as Toyota, Jeep, and Porsche tend to retain value better than many luxury sedans.

Final Thoughts

There are approximately 18,311 franchised new-car dealerships and roughly 26,500 independent used car dealerships in the United States, but today’s car buying process has increasingly shifted toward digital platforms that allow consumers to research, finance, and purchase vehicles entirely online through services. Even with these changes, many buyers still prefer visiting dealerships to see, drive, and experience vehicles in person.
