Used 2021 Subaru Legacy for Sale near Maine

How much does the 2021 Subaru Legacy cost?

Prices have softened 8.95% compared to this time last year, making it a favorable time to shop this model year.

With 569 listings available, you have a modest amount of inventory to compare before you buy. If you find a listing below $19,606.28, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2021 Subaru Legacy a good car?

Yes — the 2021 Subaru Legacy earns a 5/5 user rating and an 8.33/10 expert rating. The model scores 9/10 across Cost effectiveness and Safety.

It stands out as a practical midsize sedan with standard all-wheel drive, fuel efficiency, comfortable seats, and standard advanced safety features. That makes it a strong fit if you want a confidence-inspiring daily driver for poor weather and mainstream commuting.

The trade-offs are clear: styling is uninspired, performance is sluggish, and the interior materials can feel cheap. Even so, the Legacy’s well-rounded setup gives you a lot of everyday usefulness for the money.

29.9% of listings are priced as good or great deals, so there is still room to shop selectively.

Is the 2021 Subaru Legacy reliable?

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

The Legacy’s appeal is built around practicality, efficiency, safety, and standard all-wheel drive, and the expert review reinforces that it is a sensible, comfort-focused sedan. It also has a five-year/60,000-mile powertrain limited warranty, which adds some ownership reassurance.

Its EyeSight safety system is described as relatively easy to use, and the car’s fuel-efficient drivetrain supports low-stress daily use. For used buyers, the main long-term risk is less about core dependability and more about living with the car’s annoying alerts and its less polished interior execution.

What should I look for when buying a used 2021 Subaru Legacy?

Accident-free inventory is solid at 79.8% — always verify the vehicle history report.

You should still check the history report carefully, because accident-free listings are not the same as problem-free listings. Prioritize a pre-purchase inspection that focuses on body condition, interior wear, and how well the electronics and driver-assistance features work. Pay close attention to fit-and-finish details, since the cabin can show quality issues.

Key things to evaluate:

• Trim level: The Base trim is the most stripped-down version, while higher trims add more premium equipment and features. If you want a better-equipped cabin, look higher up the range.
• Powertrain: The standard 2.5-liter four-cylinder makes 182 horsepower and 176 pound-feet of torque, while the turbocharged 2.4-liter engine in XT trims makes 260 hp and 277 lb-ft. The base engine is fine for everyday driving, but the turbo is the better choice if you want stronger passing and hill-climbing ability.
• Safety package: Subaru EyeSight is standard and includes adaptive cruise control with lane centering, pre-collision automatic emergency braking and throttle management, and vehicle lane departure and sway warning. EyeSight Assist Monitor is also included, while reverse automatic braking and blind-spot monitoring are available.
• Infotainment: Base models use dual 7-inch displays, while Premium and higher trims get a standard 11.6-inch infotainment screen. Apple CarPlay and Android Auto are standard, and higher trims add features such as Subaru Starlink Connected Services, navigation, and a Harman Kardon premium audio system.
• Fuel efficiency: The 2.5-liter engine returns 27 mpg city, 35 mpg highway, and 30 mpg combined, while the turbocharged engine returns 24 mpg city, 32 mpg highway, and 27 mpg combined.

Which 2021 Subaru Legacy trim should I buy?

The 2021 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 entry point, and it gives you the core Legacy formula with standard all-wheel drive, standard safety tech, and the basic dual-screen setup. It makes sense if you want the lowest-cost way into the model, but it is the least upscale version.
• Premium: This is the best-value trim for many shoppers because it adds the standard 11.6-inch infotainment screen and a more complete feature set without jumping into the turbo models. If you want the sweet spot between price and equipment, this is the one to focus on.
• Sport: This trim adds a more distinctive look and 18-inch black wheels, so it suits you if you want a little more style without moving to the top end.
• Limited: This is the more comfort-oriented non-turbo choice, and it builds on the lower trims with a more upscale feel. It is a good fit if you want a nicer cabin but do not need the turbo engine.
• Limited XT: This is the first turbocharged trim, pairing the stronger 2.4-liter engine with a more premium equipment mix. Choose it if you want the best blend of power and upscale features.
• Touring XT: This is the top trim and the most fully equipped version, with the turbo engine and the richest feature set. It suits you if you want the most luxurious Legacy experience.

Subaru EyeSight is standard across the lineup, and buyers can add reverse automatic braking and blind-spot monitoring.

Is now a good time to buy a used 2021 Subaru Legacy?

This is a moderate, selective buyer’s market, so you can shop with some leverage but still need to move quickly on the right car.

• Deal availability: 29.9% of listings are priced as good or great deals.
• Inventory: There are 569 listings available.
• Price trend: Prices have softened 8.95% compared with last year.

If you find a listing below $19,606.28, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Subaru Legacy's resale value?

The current average of $19,858 sits slightly below last year's $21,809.

That softer pricing suggests the market has cooled, which can help you buy more affordably now. For a future seller, it also means you should expect resale value to depend heavily on condition, mileage, and how well the car has been maintained.

The Legacy’s standard all-wheel drive and strong safety reputation help support demand, especially among shoppers who want a practical sedan for bad weather. If you keep the car clean, well-documented, and accident-free, you should have a better shot at holding value.

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 2021 Subaru Legacy safe?

The 2021 Legacy earned the top scores in every category from the Insurance Institute for Highway Safety (IIHS), and it was also named a Top Safety Pick by the IIHS. The National Highway Traffic Administration (NHTSA) gave the Legacy a five-star overall rating.

It earns a 9/10 safety score from our experts.

Subaru EyeSight comes standard and includes adaptive cruise control with lane centering, pre-collision automatic emergency braking and throttle management, and vehicle lane departure and sway warning. EyeSight Assist Monitor is also included, and buyers can add reverse automatic braking and blind-spot monitoring.

One caveat is that the system can be annoying, with frequent beeps, flashing, and very sensitive seat-belt alerts. That does not erase the safety strength, but it does mean you should test the alerts and controls during your drive to make sure they suit you.

Should I buy a 2021 Subaru Legacy or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 29.9% of listings are priced as good or great deals.
• Accident-free inventory is solid at 79.8% — always verify the vehicle history report.
• Price trend: Prices have softened 8.95% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2021 model stands out for standard all-wheel drive, fuel efficiency, comfortable seats, and standard advanced safety features.

Consider the 2020 if:

• At $17,961, the 2020 costs less than the current year's $19,858 average.
• It leans into practicality, efficiency, safety, and standard all-wheel drive.

The bottom line: If you want the stronger overall package, the 2021 is the better pick because it combines standard AWD, strong safety, and softer pricing than last year. If your main goal is to spend less up front, the 2020 is the value-oriented alternative to compare closely.
