Best Used Cars to Buy in 2025: Reliable Picks Under $20,000

Shopping for the best used cars to buy can feel overwhelming with so many options out there. I've spent years looking at used car lots and online listings, and I've narrowed down the models that actually hold up. In this guide, I'll share my top recommendations for reliable used cars under $20,000 that you can trust.

Why Buying Used Makes Sense

New cars lose value the second you drive them off the lot. A three-year-old used car often costs thousands less than a new one, yet still has plenty of life left. Depreciation is the big reason buyers look for the best used cars to buy. You get more car for your money, and you avoid the steepest depreciation curve. Plus, insurance rates are lower on a used car. For example, a 2021 Toyota Camry might cost around $18,000 with 30,000 miles, while a new 2025 Camry starts near $28,000. That $10,000 difference can cover a lot of repairs or a nice vacation.

What to Look for in a Used Car

Before you start browsing, know what matters. Reliability is top of mind when searching for the best used cars to buy. Check owner forums and reliability ratings from sources like Consumer Reports. Look for models with a proven track record for the engine and transmission. Also consider maintenance costs. Some luxury brands may be cheap used but expensive to fix. Stick with mainstream brands like Honda, Toyota, Mazda, and Subaru for the best balance of reliability and repair costs. Always get a pre-purchase inspection from a trusted mechanic.

Best Used Cars to Buy: Sedans

Sedans are budget-friendly and fuel-efficient. The Toyota Corolla is a no-brainer. A 2020 Corolla with around 35,000 miles sells for about $15,000. It's dependable, cheap to insure, and gets great gas mileage. Another solid pick is the Honda Civic. The 2019 Civic LX with 40,000 miles runs around $16,000. It's sporty, reliable, and holds its value well. If you want something a bit more upscale, the Mazda3 offers a premium interior and fun driving dynamics. A 2020 Mazda3 with 30,000 miles is about $17,000. These three are often at the top of lists for the best used cars to buy in the sedan category.

Best Used Cars to Buy: SUVs and Trucks

SUVs and trucks hold their value better than sedans, but you can still find deals. The Toyota RAV4 is the king of compact SUVs. A 2019 RAV4 with 40,000 miles goes for roughly $19,000. It's spacious, reliable, and available with all-wheel drive. For something cheaper, the Honda CR-V is also excellent. A 2018 CR-V with 50,000 miles is around $17,000. If you need a truck, the Toyota Tacoma is legendary for durability, but prices are high. A 2017 Tacoma with 60,000 miles might cost $22,000, so you may need to stretch your budget. For a budget-friendly truck, look at the 2019 Ford Ranger. It came back in 2019 after a long hiatus, and a used example with 40,000 miles is about $18,000. These models represent the best used cars to buy in the SUV and truck segments.

Best Used Cars to Buy: Hybrids and Fuel-Savers

If you want to save even more at the pump, consider a used hybrid. The Toyota Prius is the gold standard for fuel efficiency. A 2018 Prius with 50,000 miles sells for around $15,000 and delivers 50+ mpg. The 2019 Honda Insight is another great option, with 45 mpg combined and a comfortable ride for about $16,000. For a hybrid SUV, the 2017 Toyota RAV4 Hybrid averages 33 mpg and costs roughly $18,000 with 60,000 miles. These choices rank among the best used cars to buy for drivers who prioritize gas savings and low emissions. Just remember to check the hybrid battery health. Most Toyota hybrids come with an 8-year/100,000-mile warranty, and batteries often last 150,000 miles or more.

How to Avoid a Lemon

Even the best used cars to buy can have problems if the previous owner neglected maintenance. Always check the vehicle history report for accidents and title issues. Look for consistent service records. I recommend buying from a private seller or certified pre-owned program. CPO cars come with a factory warranty and a thorough inspection. When you test drive, listen for strange noises and feel how the transmission shifts. Check the tires for uneven wear, which could indicate alignment problems. And don't be afraid to walk away if something feels off. A good deal today isn't worth a headache tomorrow. Also, consider getting a pre-purchase inspection from a mechanic who specializes in the make you're looking at. This can uncover hidden issues like worn brakes or a slipping transmission that a test drive might miss.

Final Thoughts

Finding the best used cars to buy takes a bit of research and patience, but it pays off. Stick with reliable models from Toyota, Honda, Mazda, and Subaru. Set a budget and get a pre-purchase inspection. Whether you choose a sedan, SUV, truck, or hybrid, a well-chosen used car can serve you for many years. I've owned several used cars and saved thousands compared to buying new. Start your search, test drive a few, and drive home a winner.
