Buying a used car is one of the smartest financial decisions you can make. You avoid the steep depreciation that hits new cars the moment they leave the lot, and with the right choice, you can get years of dependable transportation for a fraction of the cost of buying new.
The challenge is knowing which cars are actually worth buying. Not every used car is a good deal – some models are magnets for expensive repairs, while others just keep going mile after mile with minimal fuss. At today’s prices, $20,000 can still get you into a genuinely reliable vehicle if you know what to look for.
Here are some of the most dependable used cars you can buy for under $20,000.
1. Toyota Camry (2015–2018)
The Camry is one of the most dependable sedans ever built, and a 2015–2018 model in good condition can frequently be found under $20,000. This generation largely avoided the oil consumption issues that affected earlier models and earned strong reliability scores across the board.
You get a comfortable, spacious interior, good fuel economy, and the peace of mind that comes with Toyota’s long track record. Look for examples with service records and under 80,000 miles for the best value.
What to watch for: Transmission smoothness, brake condition, and infotainment responsiveness.
2. Honda Civic (2016–2019)
The Civic is the Camry’s natural rival in the reliability conversation, and for good reason. The 2016–2019 generation received a full redesign that brought sharper styling, improved technology, and strong safety scores; while maintaining the Civic’s reputation for durability and low running costs.
Fuel economy is excellent, parts are affordable, and mechanics everywhere are familiar with the platform. Avoid the turbocharged 1.5L models from 2017–2019 if oil dilution concerns you; the naturally aspirated engine in the LX trim is the safest bet for long-term reliability.
What to watch for: Oil dilution on turbo models, infotainment responsiveness, and CVT behavior on automatic versions.
3. Toyota Corolla (2014–2019)
If the Camry is slightly out of budget, the Corolla delivers much of the same Toyota reliability in a smaller, more affordable package. The 2014–2019 generation is well-regarded for its longevity, low maintenance costs, and straightforward ownership experience.
It won’t excite you, but it will almost certainly start every morning and get you where you’re going without drama. For commuters and budget-conscious buyers, that’s exactly the point.
What to watch for: Overall condition and service history – these cars last so long that high mileage examples are common. Focus on maintenance records over mileage alone.
4. Mazda3 (2014–2018)
The Mazda3 is one of the best-kept secrets in the used car market. It combines near-Toyota levels of reliability with genuinely engaging driving dynamics and a more premium interior feel than its price suggests. Mazda has consistently ranked among the most reliable brands in long-term studies, and the Mazda3 is the model that anchors that reputation.
You can find clean 2014–2018 examples well under $20,000, and ownership costs are low. It’s a particularly strong pick if you want something that’s reliable but doesn’t feel like a compromise.
What to watch for: Rust on older examples in northern states, and infotainment. The older MAZDA CONNECT system can feel dated.
5. Honda CR-V (2015–2017)
If you need more space than a sedan offers, the Honda CR-V is one of the most reliable compact SUVs you can buy used. The 2015–2017 generation uses a proven 2.4-liter naturally aspirated engine – avoiding the oil dilution concerns of the later turbocharged models – and delivers excellent practicality, good fuel economy, and strong resale value.
These are popular vehicles so finding a clean example requires patience, but the effort is worth it.
What to watch for: AC compressor condition, overall brake wear, and any signs of deferred maintenance.
6. Toyota RAV4 (2013–2017)
The RAV4 is the best-selling SUV in America for a reason, and older generations represent outstanding used car value. The 2013–2017 models use a simple, proven powertrain with an excellent long-term reliability record. They’re spacious, comfortable, and capable enough for light off-road use.
At under $20,000 you’ll likely be looking at higher mileage examples, but the RAV4 is well known for lasting well beyond 150,000 miles with proper maintenance.
What to watch for: Transmission condition, rust underneath on older examples, and AC system health.
7. Subaru Forester (2014–2018)
For buyers who need all-wheel drive, whether for winter driving or light trail use, the Subaru Forester is one of the best values in the used market. The 2014–2018 generation offers standard AWD, a practical and versatile interior, and good visibility. Subaru’s reliability has improved significantly over the past decade, and the Forester is one of their stronger performers.
Be aware that some Subaru engines from this era have a known head gasket sensitivity. It’s worth having a pre-purchase inspection done by a mechanic familiar with the brand.
What to watch for: Head gasket condition, oil consumption, and CVT behavior on automatic models.
8. Chevrolet Malibu (2016–2018)
If you want maximum value for your dollar, the Chevrolet Malibu punches well above its price point in the used market. The 2016–2018 generation received strong reviews for its comfortable ride, spacious interior, and improved build quality compared to earlier models. It won’t match a Camry or Civic for long-term reliability data, but it offers a lot of car for the money.
What to watch for: Transmission smoothness, electrical system condition, and any history of deferred maintenance.
Tips for Buying Any Used Car Under $20,000
Regardless of which model you choose, a few universal rules apply:
Always get a pre-purchase inspection. Before you hand over any money, have an independent mechanic — not one affiliated with the seller — inspect the vehicle. A $100–$150 inspection can save you thousands.
Check the vehicle history report. A Carfax or AutoCheck report will reveal accident history, ownership history, and whether the odometer reading is consistent with reported mileage.
Prioritize service records. A car with documented maintenance history is almost always a better buy than one without, regardless of mileage.
Don’t skip the test drive. Drive it on the highway, not just around the block. Pay attention to how it shifts, how it brakes, and whether anything feels or sounds off.
Factor in ownership costs. Purchase price is only part of the equation. Insurance rates, fuel economy, and the cost of common repairs vary significantly between models.
One More Thing to Consider: What Happens After You Buy
Even the most reliable used car will eventually need repairs. The older a vehicle gets and the more miles it accumulates, the more likely it is that something significant will need attention: a transmission, a water pump, an air conditioning compressor. These aren’t signs of a bad car. They’re just the reality of ownership.
A vehicle service contract from Complete Auto Protect can cover major mechanical repairs after your manufacturer warranty has expired, so that when something does go wrong, you’re not facing the full cost alone.
