Quick answers

Common car questions

How many miles is too many on a used car?

There is no hard cutoff. Cars average about 12,000 miles a year, so a 6-year-old car near 70,000–80,000 miles is normal. A well-maintained vehicle can pass 200,000 miles, so condition and service history matter more than the odometer alone.

Is it better to finance or lease a car?

Financing builds equity and costs less over time if you keep the car for years. Leasing lowers the monthly payment and lets you drive a newer car more often, but you own nothing at the end and face mileage limits. The right choice depends on how long you keep cars.

Which car brands are the most reliable?

In recent reliability studies from Consumer Reports and J.D. Power, Toyota, Lexus, Honda, and Mazda consistently rank near the top. These brands tend to have fewer reported problems per 100 vehicles and lower long-term repair costs.

Is an electric car cheaper to own than a gas car?

Often, yes on running costs. Charging at home is usually cheaper per mile than gas, and EVs skip oil changes and have fewer moving parts, cutting maintenance roughly in half. Higher purchase price and charging access are the main trade-offs to weigh.

How much does it cost to own a car per year?

The average American spends about $11,577 per year to own and operate a car, per AAA's 2024 Your Driving Costs study. That covers depreciation (the largest share at ~37%), fuel, insurance, maintenance, and loan interest. The true annual cost is often double what the monthly payment suggests.

What is a good APR for a car loan?

A good rate is at or below the average for your credit tier. In Q1 2026, new-car loans averaged 6.39% and used loans 11.43% nationally per Experian. Super-prime borrowers (781+) averaged about 4.55% on new cars, while subprime borrowers (501–600) averaged 13.44%.

How often should you change your oil?

Most modern cars on full synthetic oil go 7,500 to 10,000 miles between changes — Toyota recommends 10,000 miles on most models. The old 3,000-mile rule is obsolete. Follow your owner's manual or your car's oil-life monitor, not a quick-lube sticker.

Is it worth buying a hybrid car?

For drivers covering 12,000 or more miles per year, hybrids typically pay back their price premium in 3 to 5 years through fuel savings. The Toyota RAV4 Hybrid costs roughly $3,200 more than the gas version but saves about $900 a year in fuel, breaking even in under 4 years at current prices.
