Used 2020 Subaru WRX STI for Sale nearPhiladelphia, PA

How much does the 2020 Subaru WRX STI cost?

Prices have softened 2.65% compared to this time last year, making it a favorable time to shop this model year.

There are 352 listings available, which gives you a modest amount of inventory to compare before you buy.

Is the 2020 Subaru WRX STI a good car?

Yes — the 2020 Subaru WRX STI earns a 5/5 user rating and a 7.7/10 expert rating. The standout strength is Performance at 9/10.

The STI fits you best if you want a rally-inspired performance sedan with standard all-wheel drive and a manual transmission. The overview and test-drive notes both point to a car that prioritizes driver engagement, traction, and old-school character over the latest tech.

The main trade-offs are its outdated technology and the fact that the touchscreen and menus feel behind the times. It also leans hard into a firm, performance-first setup, so comfort and refinement are not its strongest suits.

With 36.9% of listings marked as good or great deals, you have some room to shop selectively.

Is the 2020 Subaru WRX STI reliable?

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

The overview describes a car that stays true to its performance heritage, and the expert notes reinforce that it remains a compelling performance sedan rather than a tech showcase. Its standard all-wheel drive and manual transmission point to a simpler, enthusiast-focused formula that can appeal if you value mechanical engagement.

The performance notes also emphasize a boxer engine layout and a sophisticated AWD system with torque vectoring and driver-controlled center differential settings, which support the STI’s durable, purpose-built character. On the cost side, the first scheduled maintenance visit is on the house.

For used buyers, the biggest long-term ownership risk is that the car’s performance-first setup and age make condition and maintenance history especially important.

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

At 68.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and then prioritize a thorough pre-purchase inspection. Focus on signs of hard use, modifications, and wear that can come with an enthusiast-owned performance sedan. It also makes sense to pay close attention to the condition of the drivetrain, suspension, brakes, and interior.

Key things to evaluate:

• Trim level: The STI’s styling is unique to the model, and the Series.White limited edition adds Ceramic White paint, matte bronze BBS 19-inch wheels, silver brake calipers, and model-specific exterior details. The interior is fairly Spartan, though the Series.White test car added Recaro front seats and Ultrasuede upholstery.
• Powertrain: The 2.5-liter turbocharged boxer-four makes 310 horsepower and 290 pound-feet of torque, and the STI is available only with a six-speed manual. Its AWD system includes torque vectoring, Subaru’s Multi-Mode Driver Controlled Center Differential, and SI-Drive.
• Safety package: The STI gets a five-star overall safety rating from NHTSA, with five stars in all crash tests except the driver’s side frontal test. It does not get EyeSight driver-assistance tech, and that suite includes forward collision warning, automatic emergency braking, adaptive cruise control, and lane-keep assist.
• Infotainment: The STI comes with a 7.0-inch touchscreen, Apple CarPlay, Android Auto, Bluetooth, SiriusXM satellite radio compatibility, and two front USB ports. The system is basic by modern standards, and the menus are text-heavy.
• Fuel efficiency: EPA ratings are 16 mpg city, 22 mpg highway, and 19 mpg combined.

Which 2020 Subaru WRX STI trim should I buy?

The 2020 Subaru WRX STI is offered in 2 trim levels: STI and WRX STI Limited.

Here's the short version:

• STI: This is the one to target if you want the core STI experience at the lower entry point. It gives you the standard performance hardware, manual transmission, and all-wheel drive that define the car, so it makes the most sense if you care most about the driving experience.
• WRX STI Limited: This trim is the better pick if you want more creature comforts and are willing to pay more for them. It starts higher and is the better fit if you want the STI formula with a more upscale feel.

The STI does not get EyeSight, and that safety-tech gap is tied to the manual-transmission setup.

Is now a good time to buy a used 2020 Subaru WRX STI?

This looks like a moderate, selective buyer’s market, so you can shop carefully and still find worthwhile listings.

• Deal availability: 36.9% of listings are priced as good or great deals.
• Inventory: There are 352 listings available.
• Price trend: Prices have softened 2.65% compared with last year.
• Clean inventory: 68.8% of listings are accident-free.

If you find a listing below $29,342, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 Subaru WRX STI's resale value?

The current average of $29,344 sits slightly below last year's $30,142.

That price movement suggests the STI has softened a bit, which can help you as a buyer today but may limit upside if you plan to resell soon. If you buy at the right price and keep the car in strong condition, you can help protect your future value.

Because this model year still has enthusiast appeal and a clear identity, well-kept examples should remain easier to move than neglected ones. Mileage, condition, and maintenance history will matter a lot when it comes time to sell.

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 WRX STI safe?

The 2020 Subaru WRX STI earns five-star ratings from NHTSA, with five stars in all crash tests except the driver’s side frontal test.

It earns a 7/10 safety score from our experts.

The STI does not get the EyeSight driver-assistance suite, and that means it misses out on forward collision warning, automatic emergency braking, adaptive cruise control, and lane-keep assist. That gap is tied to the manual-transmission setup.

The main safety caveat is that the STI’s available safety tech is limited compared with some rivals, so you should not expect a full modern driver-assistance package.

Should I buy a 2020 Subaru WRX STI 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:

• 36.9% of listings are priced as good or great deals.
• At 68.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 2.65% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2020 keeps the STI’s rally-inspired character, standard all-wheel drive, and manual-transmission focus.

Consider the 2021 if:

• At $33,016, the 2021 costs more than the current year's $29,344 average.
• It adds a more up-to-date feel and some infotainment updates.

The bottom line: If you want the better value, the 2020 is the smarter starting point because it delivers the STI formula at a lower average price. If you’re willing to spend more for a newer example, the 2021 is the secondary path to consider.
