How much does the 2021 Subaru Legacy cost?

Is the 2021 Subaru Legacy a good car?

Yes — you’re looking at a 5/5 user-rated car with an expert rating of 8.33/10. The model scores 9/10 across Cost effectiveness and Safety.

The Legacy stands out for standard all-wheel drive, fuel efficiency, comfortable seats, and standard advanced safety features, which makes it especially appealing if you want everyday usability and extra confidence in poor weather. The trade-offs are clear: styling is uninspired, performance is sluggish, and the interior materials can feel cheap.

Is the 2021 Subaru Legacy reliable?

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

The Legacy’s safety and practicality focus supports its reputation as a dependable daily driver, and the expert review also highlights its fuel efficiency and standard all-wheel drive as core strengths. Its five-year/60,000-mile powertrain limited warranty adds another layer of reassurance for used buyers.

The main long-term ownership risk is that the car’s less polished interior and annoying safety alerts may affect how satisfied you feel over time.

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

Accident-free inventory is solid at 80.4% — always verify the vehicle history report.

You should still run a history report on any car you’re considering, even if it looks clean on paper. Prioritize a pre-purchase inspection so you can check for fit-and-finish issues, interior wear, and any signs that the safety tech or electronics have been overworked. Focus on overall condition, because the Legacy’s value proposition depends heavily on whether it still feels well-kept.

Key things to evaluate:

• Trim level: Base models get dual 7-inch displays, while Premium and higher trims add the 11.6-inch infotainment screen and more upscale equipment. The base trim is the most stripped-down version, so make sure the feature set matches what you want.
• Powertrain: The Base, Premium, Sport, and Limited use a 2.5-liter four-cylinder with 182 horsepower and 176 pound-feet of torque, while Limited XT and Touring XT use a turbocharged 2.4-liter with 260 hp and 277 lb-ft. The turbo is the better pick 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 above get an 11.6-inch screen. Apple CarPlay and Android Auto are standard, and higher trims add features like navigation, Subaru Starlink Connected Services, and a Harman Kardon audio system.
• Fuel efficiency: The 2.5-liter engine returns 27 mpg city, 35 mpg highway, and 30 mpg combined. The turbocharged engine gets 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 Legacy’s core value proposition: 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’s the least equipped version.
• Premium: This is the best-value trim for most shoppers because it adds the 11.6-inch infotainment screen and a more complete feature set without jumping into turbo pricing. If you want the strongest balance of equipment and price, start here.
• Sport: This trim adds a more distinctive look and 18-inch black wheels, making it the choice if you want a little more visual flair without moving to the turbo models.
• Limited: This is the more upscale non-turbo choice, and it suits you if you want a richer cabin and more comfort-oriented equipment while staying with the standard engine.
• Limited XT: This is the first trim with the turbocharged engine, so it’s the one to choose if you want stronger acceleration and more confident highway passing.
• Touring XT: This is the top-end version, pairing the turbo engine with the most premium equipment in the lineup for buyers who want the most fully loaded Legacy.

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 looks like a moderate, selective buyer’s market, so you have room to shop carefully without rushing.

• Deal availability: 30.2% of listings are priced as good or great deals.
• Inventory: There are 562 listings available.
• Price trend: Prices have softened 8.97% compared with last year.
• Clean inventory: 80.4% of listings are accident-free.

If you find a listing below $19,606, 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 $19,772 sits slightly below last year's $21,721.

That price movement suggests the market has cooled, which can work in your favor if you’re buying now but may pressure future resale if you plan to sell soon. If you own one for a few years, the Legacy’s value will likely depend on how well it holds up against newer, better-equipped alternatives in the midsize-sedan class. Strong condition and a clean history should matter a lot when it’s time to list it.

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, including crashworthiness, crash-avoidance tech, and LATCH system ease of use, and it was named a Top Safety Pick by the IIHS. It also earns a five-star overall rating from NHTSA.

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

Subaru EyeSight is standard, and it 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 EyeSight system can be annoying because of frequent beeps, flashing, and very sensitive seat-belt alerts.

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:

• 30.2% of listings are priced as good or great deals.
• Accident-free inventory is solid at 80.4% — always verify the vehicle history report.
• Price trend: Prices have softened 8.97% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2021 Legacy combines standard AWD, fuel efficiency, and standard advanced safety features in a value-oriented package.

Consider the 2020 if:

• At $17,851, the 2020 costs less than the current year's $19,772 average.
• It leans into practicality, efficiency, safety, and standard all-wheel drive.

The bottom line: Choose the 2021 if you want the stronger overall market position, better safety confidence, and a still-reasonable price. Consider the 2020 if your priority is saving money up front and you’re comfortable with a slightly older version of the same practical formula.
