Used 2015 Subaru WRX STI for Sale nearPortland, ME

How much does the 2015 Subaru WRX STI cost?

Prices have held steady compared to this time last year, signaling a stable and predictable market for this model year.

There are 147 listings available, which gives you a modest amount of inventory to compare before you buy.

Is the 2015 Subaru WRX STI a good car?

Yes — the 5/5 user rating points to strong owner satisfaction. The 2015 Subaru WRX STI stands out as a focused performance sedan with rally roots and standard all-wheel drive, and it is aimed at buyers who want something fast, practical, and unusual. Its appeal comes from a turbocharged engine, a six-speed manual transmission, and Subaru’s symmetrical all-wheel drive system with a Driver Controlled Center Differential, while still offering everyday conveniences like navigation, Bluetooth, and automatic climate control. The tradeoffs are clear, though: the ride is stiff, the back seat is tight, the trunk is nothing remarkable, and the sound system is underwhelming. 34.0% of listings are priced as good or great deals, which gives you some room to shop selectively.

Is the 2015 Subaru WRX STI reliable?

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

The 2015 Subaru WRX STI is built around a focused performance setup with standard all-wheel drive, a manual transmission, and driver-oriented hardware that supports confident everyday use. Its identity is rooted in rally-inspired engineering, and the car is presented as a direct offshoot of Subaru’s World Rally Championship efforts, which reinforces its purpose-built character. For used buyers, the main long-term ownership risk is that a performance car like this may have been driven hard, so condition and maintenance history matter a lot.

What should I look for when buying a used 2015 Subaru WRX STI?

At 58.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report so you can confirm accident records, title status, and ownership history before you get too far into the process. After that, prioritize a thorough pre-purchase inspection, especially on a performance sedan where wear can show up in the drivetrain, suspension, and brakes. Focus on overall condition and maintenance evidence, since the car’s appeal depends heavily on how well it has been cared for.

What is the 2015 Subaru WRX STI's resale value?

The current average of $19,635 sits slightly above last year's $19,485.

That kind of movement suggests the market has been stable rather than volatile, which is helpful if you plan to sell later. A steady price trend can make it easier to estimate your exit value and avoid sharp depreciation surprises. Because demand tends to stay healthier for cars with strong owner satisfaction, this model year’s appeal should continue to support buyer interest over time.

Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.
