Used 2015 Subaru WRX STI for Sale near Illinois

How much does the 2015 Subaru WRX STI cost?

Prices are up 3.18% year-over-year — a sign of continued demand for this model year.

There are 139 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 — 5/5 is a strong user rating for this model year, and the overview points to a focused, rally-inspired performance sedan that still works for everyday use. Standard all-wheel drive, serious performance hardware, and practical usability make it appealing if you want a fast car that can handle more than just dry pavement. The tradeoff is a rough ride and cheap interior materials, so it fits you best if performance and all-weather capability matter more than comfort and cabin polish. There are 27.3% good or great deals in the market, 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 overview suggests a car that can be rewarding to own if you value its performance-first character and practical all-wheel-drive setup. At the same time, it has often been heavily used, abused, or modified, so condition matters a great deal when you shop. For used buyers, that means long-term ownership risk is tied less to the badge and more to how carefully the specific car was maintained and driven.

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

At 58.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and confirm whether the car has been in any accidents, modified, or used hard. A pre-purchase inspection should focus on signs of abuse, uneven wear, and any evidence that the car has been driven beyond normal daily use. Because condition matters so much on this model, you should prioritize mechanical health and maintenance records over cosmetic appeal.

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

This is a seller’s market, so you should act selectively and be ready to move when a strong listing appears.

• Deal availability: 27.3% of listings are priced as good or great deals.
• Inventory: There are 139 listings available.
• Price trend: Prices are up 3.18% year-over-year.
• Clean inventory: 58.3% of listings are accident-free.

If you find a listing below $18,442, 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 $19,576 sits slightly above last year's $18,973.

That upward move suggests the market still places solid value on this model year, which can help support resale if you buy carefully. Because demand remains steady and inventory is not especially deep, a well-kept example should stay relatively easy to move later. If you choose a clean, unmodified car with good documentation, you are more likely to protect your exit value.

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:

• 27.3% of listings are priced as good or great deals.
• At 58.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices are up 3.18% year-over-year.
• Owners rate it 5/5 — a strong satisfaction signal.

The bottom line: Buy the 2015 if you want the strongest mix of performance, practicality, and market support in this price band, especially if you can verify a clean history and solid maintenance. If you are more price-sensitive, you may want to compare nearby years and focus on the best-documented example rather than the lowest sticker price.
