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’s aimed at you if you want something fast, practical, and unusual. Its appeal comes from the turbocharged engine, six-speed manual transmission, and symmetrical all-wheel drive system, while the tradeoffs are a stiff ride, a tight back seat, and a trunk that is nothing remarkable. 31.0% 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 car’s hardware is straightforward and enthusiast-focused, with a turbocharged boxer engine, a manual transmission, and Subaru’s all-wheel-drive system, which can be appealing if you want a durable-feeling performance setup. For used buyers, the main long-term ownership risk is that a hard-driven performance car can hide wear, so condition and maintenance history matter a lot.

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

At 57.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should run a vehicle history report before you commit, then prioritize a pre-purchase inspection from a mechanic who can evaluate the drivetrain, suspension, and brakes. Focus on overall condition, because a performance sedan like this can vary widely depending on how it was driven and maintained.

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

This looks like a moderate market, so you can be selective without expecting a deep bargain on every listing.

• Deal availability: 31.0% of listings are priced as good or great deals.
• Inventory: There are 155 listings available.
• Price trend: Prices are up 1.62% year-over-year.
• Clean inventory: 57.4% of listings are accident-free.

If you find a listing below $18,452, 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 $19,872 sits slightly above last year's $19,555.

That price movement suggests the market has held up reasonably well, which can help you if you decide to sell later. Because demand is still supported by the model’s performance-focused identity and all-wheel-drive appeal, a clean, well-kept example should remain easier to market than a neglected one. If you buy carefully and keep documentation, you’re more likely to protect value 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.

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:
