Used 2020 Subaru Legacy for Sale nearSaint Louis, MO

How much does the 2020 Subaru Legacy cost?

Prices have softened 9.83% compared to this time last year, making it a favorable time to shop this model year.

There are 516 listings available, which gives you a solid pool of used examples to compare.

Is the 2020 Subaru Legacy a good car?

Yes — with a 5/5 user rating and a 7.83/10 expert rating, the 2020 Subaru Legacy lands as a strong all-around pick. The standout strength is Safety at 10/10.

The Legacy fits you well if you want a practical midsize sedan with standard all-wheel drive, fuel-efficient engines, and an easy-to-use interior. It also brings strong value for money and a family-friendly focus, though the tech can feel unintuitive and the base engine is underwhelming.

The main trade-offs are the complicated infotainment setup and the lack of punch from the standard powertrain. If you care more about everyday usefulness, all-weather capability, and safety than driving excitement, it makes a lot of sense.

Good and great deals account for 32.6% of listings, which suggests there are still worthwhile opportunities in the market.

Is the 2020 Subaru Legacy reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction.

The Legacy’s reliability case is built around its practical design, standard all-wheel drive, and straightforward everyday mission. Its expert evaluation also points to strong value and a focus on safety, which usually matters to used buyers who want a car that feels dependable over time.

The performance notes also support that impression: the base powertrain is efficient, the transmission is responsive enough for daily use, and the chassis is described as surprisingly good. On the ownership side, the cost-effectiveness notes suggest Subaru packed in a lot of equipment for the money, which can help reduce regret after purchase.

For used buyers, the biggest long-term risk is living with the car’s frustrating tech and the weaker base engine if you choose the wrong trim.

What should I look for when buying a used 2020 Subaru Legacy?

At 73.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and confirm whether any prior damage was repaired properly. After that, prioritize a careful inspection of body panels, paint consistency, and signs of uneven wear, since condition can vary meaningfully from one listing to another. It also makes sense to test the infotainment system and driver-assistance features during your drive, because those are among the car’s most important day-to-day touchpoints.

Key things to evaluate:

• Trim level: The base trim comes well equipped with remote keyless entry, Bluetooth, dual 7-inch touchscreens with Apple CarPlay and Android Auto, automatic climate control, voice recognition, Subaru EyeSight, and 17-inch steel wheels with plastic covers. Premium adds 17-inch alloy wheels, power side mirrors, four USB ports, the 11.6-inch touchscreen, a leather-wrapped steering wheel and shift knob, dual-zone automatic climate control, a power moonroof, and 10-way power front seats, while also including the All-Weather Package with heated seats, heated mirrors, and a windshield wiper de-icer. Sport adds 18-inch alloys, a trunk spoiler, a more aggressive front fascia, LED fog lights, red contrast stitching, leather dash cladding, and aluminum alloy pedal covers. Limited adds adaptive LED headlights, auto power up/down for all four windows, an 8-way power front passenger seat, driver memory settings, perforated leather upholstery, and heated rear seats. Limited XT adds the turbocharged engine, dual tailpipes, a distracted-driving monitor, and a heated steering wheel. Touring XT adds power-folding mirrors with integrated turn signals, full Nappa leather upholstery, and heated and ventilated front seats.
• Powertrain: The base, Premium, Sport, and Limited trims use a 2.5-liter boxer 4-cylinder with 182 horsepower and 176 pound-feet of torque, paired with standard AWD and a CVT with manual mode and paddle shifters. The Limited XT and Touring XT use a 2.4-liter turbocharged boxer 4-cylinder with 260 horsepower and 270 pound-feet of torque, also paired with a CVT and paddle shifters. The base engine is efficient, but it can feel noisy and strained when you push for highway speed.
• Safety package: Subaru EyeSight is standard and includes forward-collision warning, lane-departure warning, and adaptive cruise control. Other standard safety features include front- and side-impact airbags, traction control, a reversing camera, and a tire pressure monitoring system. The base trim already gets the core safety suite, so you do not need to move up just to get the main driver-assistance features.
• Infotainment: The base trim uses dual 7-inch touchscreens with Apple CarPlay and Android Auto. Higher trims bring the 11.6-inch touchscreen and Starlink infotainment system, but the setup can be cumbersome, and some functions require too many steps. The system also supports over-the-air CarPlay updates.
• Fuel efficiency: The base engine returns 27 mpg city, 35 highway, and 30 combined. In testing, it was observed at 29 mpg in mixed driving. The turbocharged engine drops to 24 city, 32 highway, and 27 combined.

Which 2020 Subaru Legacy trim should I buy?

The 2020 Subaru Legacy is offered in 6 trim levels: base, Premium, Sport, Limited, Limited XT, and Touring XT.

Here's the short version:

• base: This is the value play if you want the Legacy’s core strengths without paying for extras. You still get standard AWD, EyeSight, Apple CarPlay and Android Auto, and the basic convenience features that make the car easy to live with.
• Premium: This is the best-value trim for most shoppers because it adds the 11.6-inch touchscreen, more USB ports, a power moonroof, dual-zone climate control, and the All-Weather Package with heated seats, heated mirrors, and a windshield wiper de-icer.
• Sport: Choose this if you want a more distinctive look and a few extra style touches, including 18-inch wheels, LED fog lights, a trunk spoiler, and sportier interior details.
• Limited: This is the comfort-focused upgrade, adding adaptive LED headlights, driver memory settings, heated rear seats, and leather upholstery.
• Limited XT: Pick this if you want the turbocharged engine plus a few extra features such as a heated steering wheel and a distracted-driving monitor.
• Touring XT: This is the top choice if you want the most upscale Legacy, with the turbo engine, Nappa leather, heated and ventilated front seats, and power-folding mirrors.

Subaru EyeSight is standard across the lineup, so you do not need to move up for the core safety suite.

Is now a good time to buy a used 2020 Subaru Legacy?

This looks like a moderate, selective buyer’s market, so you can shop patiently but still move quickly on the right car.

• Deal availability: 32.6% of listings are priced as good or great deals.
• Inventory: There are 516 listings available.
• Price trend: Prices have softened 9.83% compared with last year.
• Clean inventory: 73.4% of listings are accident-free.

If you find a listing below $17,704, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 Subaru Legacy's resale value?

The current average of $17,704 sits slightly below last year's $19,635.

That price movement suggests the Legacy has become more affordable for buyers, which can make it a tougher sell if you are trying to maximize your return quickly. On the other hand, a lower entry price can help keep demand steady among shoppers who want standard AWD and strong safety without paying new-car money.

If you plan to sell later, trim choice and condition will matter a lot. Well-kept examples with desirable equipment should be easier to market than higher-mileage cars with the base engine and less appealing tech.

Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.

Is the 2020 Subaru Legacy safe?

The 2020 Subaru Legacy earns a 10/10 safety score from our experts.

It comes standard with Subaru’s EyeSight suite of driver-assistance features, including forward-collision warning, lane-departure warning, and adaptive cruise control. Other standard safety equipment includes a full array of front- and side-impact airbags, traction control, a reversing camera, and a tire pressure monitoring system.

The base trim already includes the core safety package, so you do not need to step up to a higher trim for the main driver-assistance features. If safety is your top priority, that makes the Legacy especially appealing as a used buy.

Should I buy a 2020 Subaru Legacy or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 32.6% of listings are priced as good or great deals.
• At 73.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 9.83% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• It combines standard AWD, strong safety, and practical everyday usability.

Consider the 2021 if:

• At $19,588, the 2021 costs more than the current year's $17,704 average.
• It keeps standard AWD while leaning into comfort, safety, and everyday practicality.

The bottom line: If you want the better value, the 2020 is the smarter starting point because prices are softer and inventory is healthy. If you are willing to spend more for a newer model year, the 2021 is the cleaner alternative, but price-sensitive buyers should focus on the 2020 and shop condition carefully.
