Used 2020 Subaru WRX STI for Sale nearPhiladelphia, PA

How much does the 2020 Subaru WRX STI cost?

Prices have softened 1.90% compared to this time last year, making it a favorable time to shop this model year.

There are 341 listings available, which suggests you have some room to compare condition and mileage across the market.

If you find a listing below $29,525.52, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2020 Subaru WRX STI a good car?

Yes — the 2020 Subaru WRX STI earns a 5/5 user rating and a 7.67/10 expert rating. The standout strength is Performance at 9/10.

It’s a rally-inspired performance sedan with standard all-wheel drive, a manual transmission, and a focus on driving enjoyment rather than modern polish. The trade-offs are clear: the technology is outdated, and the shifter and steering are not as polished as the rest of the car’s performance hardware.

For you, that means the STI makes the most sense if you want an involving, old-school performance car with real all-weather capability. 26.7% of listings are priced as good or great deals, so there is some market flexibility if you shop carefully.

Is the 2020 Subaru WRX STI reliable?

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

The STI’s appeal is built around a durable-feeling, performance-first formula: a boxer engine, standard all-wheel drive, and a cabin that is described as fairly Spartan but likely to hold up to long-term abuse. The expert test drive data also points to a car that is focused on driver engagement more than luxury or cutting-edge tech.

Its performance hardware is substantial, and the manual-only setup keeps the car simple in one important respect. The ownership risk for used buyers is that a car this enthusiast-focused may have been driven hard, so condition and maintenance history matter a lot.

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

At 68.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

Start with a vehicle history report and make sure you understand any accident, repair, or modification history before you go further. Then prioritize a pre-purchase inspection, especially on the drivetrain, suspension, brakes, and tires, since this model is built for hard driving. You should also pay close attention to interior wear and overall condition, because enthusiast ownership can leave a mark even when the car looks clean at first glance.

Key things to evaluate:

• Trim level: The STI’s styling is more aggressive than the standard WRX, with unique bodywork, a big rear wing, and a more purposeful interior. The Series.White limited edition adds Ceramic White paint, matte bronze BBS 19-inch wheels, silver brake calipers, black exterior and rear badging, a model-specific grille, Recaro front seats, and Ultrasuede upholstery.
• Powertrain: You get a 2.5-liter turbocharged boxer-four with 310 horsepower and 290 pound-feet of torque, plus a six-speed manual only. The AWD system includes torque vectoring and Subaru’s Multi-Mode Driver Controlled Center Differential for adjustable torque split.
• Safety package: EyeSight driver-assistance tech is not available with the manual transmission, so you do not get forward collision warning, automatic emergency braking, adaptive cruise control, or lane-keep assist.
• Infotainment: The STI uses a 7.0-inch touchscreen with Apple CarPlay, Android Auto, Bluetooth, SiriusXM satellite radio, and two front USB ports. The system is functional, but the screen is small and the menus are text-heavy.
• Fuel efficiency: EPA ratings are 19 mpg combined, 16 mpg city, and 22 mpg highway.

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 core choice if you want the STI experience without paying extra for added comfort equipment. It gives you the full performance formula, including the turbocharged engine, six-speed manual, and standard all-wheel drive, while keeping the car focused on driving rather than luxury.
• WRX STI Limited: This is the better-value pick if you want more creature comforts and can stretch your budget. It starts higher and is the trim to consider if you want a more upscale-feeling STI without changing the car’s basic character.

The safety package note is important here: EyeSight is not available on manual-transmission STI models.

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 with some leverage if you stay disciplined.

• Deal availability: 26.7% of listings are priced as good or great deals.
• Inventory: There are 341 listings available.
• Price trend: Prices have softened 1.90% compared with last year.
• Clean inventory: 68.6% of listings are accident-free.

If you find a listing below $29,525.52, 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 $30,930 sits slightly below last year's $31,529.

That tells you the market has softened a bit, which can help you buy more confidently now. For a future seller, it suggests there is still demand, but pricing power is not as strong as it was a year ago. If you keep the car clean, stock, and well documented, you should be in a better position than owners of heavily modified or neglected examples.

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 a five-star overall rating from NHTSA, with five-star ratings 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 because its manual transmission prevents those features from being offered. That means you miss out on forward collision warning, automatic emergency braking, adaptive cruise control, and lane-keep assist. The IIHS has not tested the STI itself, though the base WRX received a top “good” result in all crash tests and a Top Safety Pick rating when equipped with EyeSight.

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:

• 26.7% of listings are priced as good or great deals.
• At 68.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 1.90% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2020 keeps the STI formula focused on manual, rally-inspired performance with standard all-wheel drive.

Consider the 2021 if:

• At $33,803, the 2021 costs more than the current year's $30,930 average.
• It keeps the same performance-first personality while asking for a higher budget.

The bottom line: If you want the better value, the 2020 is the smarter buy because prices have eased and inventory is available. If you are willing to spend more for a newer example, the 2021 is the secondary path, but the 2020 already delivers the core STI experience without the extra cost.
