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 134 listings available, which suggests a modest but workable amount of inventory for shoppers comparing condition and mileage.

If you find a listing below $18,452.40, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2015 Subaru WRX STI a good car?

Yes — the 5/5 user rating points to strong owner satisfaction for this model year. The overview describes it as a rally-inspired performance sedan that still works for everyday use, with standard all-wheel drive and a performance-first setup that includes the Driver Controlled Center Differential and Subaru Intelligent Drive. It also highlights a practical side, with enough cargo room and back-seat space to serve as a real-world sedan, even if the ride is stiff and the cabin is not especially plush. With 27.6% of listings marked as good or great deals, you have 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 overview emphasizes a focused performance formula built around standard all-wheel drive, a turbocharged 2.5-liter boxer four-cylinder engine, a six-speed manual transmission, and Brembo performance brakes. That kind of hardware can be rewarding, but it also means you should expect a used example to have been driven hard, so condition and maintenance history matter a lot for long-term ownership risk.

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

At 59.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should run a vehicle history report before you get too far into the process, then prioritize a pre-purchase inspection from a mechanic who can assess signs of hard use. Focus on overall condition, maintenance records, and evidence of wear that would be consistent with enthusiastic driving, since this model’s performance-oriented nature makes careful screening especially important.

Is now a good time to buy a used 2015 Subaru WRX STI?

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

• Deal availability: 27.6% of listings are priced as good or great deals.

If you find a listing below $18,452.40, that's toward the low end of the year-round range and worth acting on quickly.

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

The current average of $19,507 sits slightly below last year's $19,543.

That small decline suggests the market has been fairly stable, which can help future sellers because it points to predictable pricing rather than sharp depreciation swings. If you buy well and keep the car in strong condition, you are more likely to preserve value in a market that has not shown much volatility. The limited year-over-year change also suggests that buyers continue to see this model year as a desirable performance sedan rather than a bargain-bin option.

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

Should I buy a 2015 Subaru WRX STI or consider a different year?

If you're weighing the 2015 against nearby model years, here's how to think about it:

Choose the 2015 if:

• 27.6% of listings are priced as good or great deals.
• At 59.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have held steady compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

The bottom line: If you want the rally-inspired performance sedan with strong owner satisfaction and a stable price profile, the 2015 is a solid primary target. If you are especially price-sensitive, keep shopping within the surrounding years and compare condition closely, since the best value may come down to the individual listing rather than the badge year alone.
