Used 2020 Subaru WRX STI for Sale nearPhoenix, AZ

How much does the 2020 Subaru WRX STI cost?

Prices have softened 3.59% compared to this time last year, making it a favorable time to shop this model year.

There are 358 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 7.67/10 expert rating. The standout strength is Performance at 9/10.

The overview and expert test drive data both point to the same core appeal: this is a rally-inspired performance sedan with standard all-wheel drive, a manual transmission, and a driving experience that prioritizes involvement over polish. It’s also described as fun to drive and as a higher-performance version of the Subaru WRX, which fits the enthusiast-first mission.

The trade-offs are clear, though. The technology is dated, and the cabin is more functional than luxurious, so you should expect old-school character rather than modern refinement.

With 34.1% of listings priced as good or great deals, the market gives you 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 and expert test drive data both frame the WRX STI as a durable, enthusiast-focused performance sedan rather than a delicate luxury car. Its old-school layout and straightforward mission suggest a car built around driving engagement, not complexity.

The performance notes also emphasize the boxer engine, standard all-wheel drive, and a manual transmission, which are all part of the model’s long-running formula. The expert test drive data also notes that the interior is fairly Spartan but likely to hold up to long-term abuse.

If you’re shopping used, the biggest long-term ownership risk is finding a car that hasn’t been driven hard, modified heavily, or neglected.

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

At 66.5% 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, especially if the car has been modified or driven aggressively. Focus on wear items, signs of abuse, and whether the car’s condition matches its mileage and price.

Key things to evaluate:

• Trim level: The standard STI is fairly Spartan, while the Series.White adds model-specific paint, BBS wheels, silver brake calipers, black exterior badging, a model-specific grille, Recaro front seats, and Ultrasuede upholstery. The limited-edition Series.White is the most distinctive choice if you want the most special-feeling version.
• 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 and Subaru’s Multi-Mode Driver Controlled Center Differential.
• Safety package: The STI does not get EyeSight driver-assistance tech, and those features are not available with the manual transmission.
• Infotainment: Standard equipment includes a 7.0-inch touchscreen, Apple CarPlay, Android Auto, Bluetooth, SiriusXM satellite radio compatibility, and two front USB ports.
• Fuel efficiency: EPA ratings are 19 mpg combined (16 mpg city, 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 enthusiast pick if you want the full STI experience without paying for extra comfort features. It gives you the standard performance hardware and the manual-only formula that defines the car.
• WRX STI Limited: This is the better-value choice if you want more creature comforts and a more upscale feel without leaving the STI formula behind.

The safety content also notes that EyeSight driver-assistance tech is not available on manual-transmission cars, so you should not expect that package on this model.

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

This is a moderate market for selective buyers, so you can shop carefully and still find worthwhile listings.

• Deal availability: 34.1% of listings are priced as good or great deals.
• Inventory: There are 358 listings available.
• Price trend: Prices have softened 3.59% compared with last year.
• Clean inventory: 66.5% of listings are accident-free.

If you find a listing below $29,498, 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 $30,191 sits slightly below last year's $31,315.

That price movement suggests the market has eased a bit, which can help you buy more confidently now. For a future seller, it also means you should expect resale value to depend heavily on condition, mileage, and whether the car has been kept stock and well maintained.

Because this model has enthusiast appeal, clean examples should continue to draw attention from buyers who want a manual, all-wheel-drive performance sedan. 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 safety content also says the base WRX received the highest “good” rating in all IIHS crash tests, but the STI itself was not tested by IIHS. The STI also misses out on EyeSight driver-assistance tech, which includes forward collision warning, automatic emergency braking, adaptive cruise control, and lane-keep assist.

That means you get strong crash-test performance, but you should not expect the latest active-safety suite on this manual-transmission performance sedan.

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:

• 34.1% of listings are priced as good or great deals.
• At 66.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 3.59% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2020 stands out for its rally-inspired character, standard all-wheel drive, and manual-transmission enthusiast focus.

Consider the 2021 if:

• At $33,305, the 2021 costs more than the current year's $30,191 average.
• It adds a more refined take on the same performance-sedan formula, with updated infotainment already in place.

The bottom line: If you want the better value, the 2020 is the smarter buy because prices have softened and the model still delivers the core STI experience. If you’re willing to pay more for a newer example, the 2021 is the cleaner alternative for buyers who want to stay in the STI family with a slightly fresher feel.
