How much does the 2020 Subaru Legacy cost?

Prices have softened 12.09% compared to this time last year, making it a favorable time to shop this model year.

There are 508 listings available, which suggests a healthy amount of inventory to compare.

Is the 2020 Subaru Legacy a good car?

Yes — the 2020 Subaru Legacy earns a 5/5 user rating and a 7.8/10 expert rating. 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. The expert review also points to strong value for money and a safety-focused setup, which lines up with shoppers who prioritize everyday usefulness over flash.

The main trade-offs are the unintuitive technology and the underwhelming base engine. If you want a sedan that emphasizes traction, efficiency, and safety, the Legacy makes a strong case; if you care most about polished tech or stronger acceleration, you may want to look more closely at alternatives.

34.8% of listings are priced as good or great deals, which gives you some room to shop selectively.

Is the 2020 Subaru Legacy reliable?

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

The Legacy’s reliability story is tied to its practical design, standard all-wheel drive, and safety-first approach. The expert review also emphasizes fuel-efficient engines and a straightforward, everyday-use layout, which are the kinds of traits that usually support steady ownership confidence.

Its performance notes suggest the base powertrain is adequate for daily driving, but not especially strong when you need highway passing power. For used buyers, that means long-term ownership risk is less about mechanical drama and more about whether the car’s tech and powertrain feel satisfying enough for your needs.

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

At 65.6% 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. A pre-purchase inspection is worth prioritizing, especially if you’re considering a higher-mileage example or one with a lower asking price. Focus your condition check on the interior tech, since the Legacy’s controls can be frustrating even when everything is working correctly.

Key things to evaluate:

• Trim level: The base trim comes with remote keyless entry, Bluetooth connectivity, dual 7-inch touchscreens with Apple CarPlay and Android Auto, 17-inch steel wheels with plastic covers, automatic climate control, voice recognition, and Subaru EyeSight. The Premium adds 17-inch alloy wheels, power side mirrors, four USB ports, a large 11.6-inch touchscreen, a leather-wrapped steering wheel and shift knob, dual-zone automatic climate control, a standard power moonroof, 10-way power front seats, and the All-Weather Package with heated seats, heated mirrors, and a windshield wiper de-icer.
• 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. A 2.4-liter turbocharged boxer 4-cylinder with 260 horsepower and 270 pound-feet of torque is available in the Limited XT and Touring XT.
• Safety package: Subaru EyeSight is standard and includes forward-collision warning, lane-departure warning, and adaptive cruise control. Other standard safety features include a full array of front- and side-impact airbags, traction control, a reversing camera, and a tire pressure monitoring system.
• Infotainment: The Legacy uses a massive 11.6-inch touchscreen on higher trims, while the base trim gets dual 7-inch touchscreens with Apple CarPlay and Android Auto. The system includes over-the-air CarPlay functionality, but the review notes that the interface can be frustrating to use.
• Fuel efficiency: The base engine returns 27 mpg city, 35 highway, and 30 combined. 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 lowest entry price and still want standard AWD, EyeSight, Apple CarPlay, Android Auto, and the core safety and convenience features. It makes the most sense if you care more about capability and price than upscale amenities.
• Premium: This is the best-value trim because it adds the 11.6-inch touchscreen, 10-way power front seats, a power moonroof, dual-zone climate control, extra USB ports, and the All-Weather Package. If you want the most useful upgrades without jumping too far in price, this is the one to target.
• Sport: Choose this if you want a more expressive look, with 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: This trim is the comfort-and-convenience step up, adding 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: This is the better pick if you want the stronger turbocharged engine along with extras like dual tailpipes, a distracted-driving monitor, and a heated steering wheel.
• Touring XT: This is the top choice if you want the most upscale version, with the turbo engine, power-folding mirrors with integrated turn signals, full Nappa leather upholstery, and heated and ventilated front seats.

Subaru EyeSight is standard, so you get the core safety suite even on the base trim.

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

The market looks moderately favorable for selective buyers.

• Deal availability: 34.8% of listings are priced as good or great deals.
• Inventory: There are 508 listings available.
• Price trend: Prices have softened 12.09% compared with last year.
• Clean inventory: 65.6% of listings are accident-free.

If you find a listing below $17,200, 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 $17,200 sits slightly below last year's $19,566.

That price movement suggests the Legacy has become more buyer-friendly in the used market, which can make it easier for future sellers to attract interest if they price competitively. The softer trend also means you may not see rapid appreciation, so resale value will depend more on condition, mileage, and trim than on market momentum alone.

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 safety setup is a major strength, especially because it’s standard rather than reserved for higher trims. If you’re shopping used, that broad standard equipment list is one of the Legacy’s biggest advantages.

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:

• 34.8% of listings are priced as good or great deals.
• At 65.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 12.09% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2020 stands out for standard all-wheel drive, strong safety, and excellent value for money.

Consider the 2021 if:

• At $18,710, the 2021 costs more than the current year's $17,200 average.
• It adds a broader appeal with standard all-wheel drive, comfortable seats, and fuel efficiency.

The bottom line: If you want the better value today, the 2020 is the stronger buy because pricing has softened and inventory is available. If you’re willing to spend more for a newer model year, the 2021 is the cleaner alternative for shoppers who want to stay close to the Legacy formula.
