At 59.7% 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 separate clean examples from cars with accident records. After that, prioritize a pre-purchase inspection, especially on the drivetrain, suspension, brakes, and signs of hard use. Because this model is performance-focused, you should pay close attention to overall condition and maintenance quality rather than assuming every example has been treated gently.

The current average of $25,416 sits slightly above last year's $25,365.

That small increase suggests the market has stayed resilient, which is a good sign if you plan to sell later. Stable pricing also means you are less likely to see a sharp drop in value just because time passes. If you keep the car in strong condition and avoid a rough ownership history, you should be better positioned to hold buyer interest when it is time to list it.

Vehicles with solid owner satisfaction ratings, like this model year's 4.33/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2018 Subaru WRX STI or consider a different year?

If you're weighing the 2018 against nearby model years, here's how to think about it:

Choose the 2018 if:

• 28.3% 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 4.33/5 — a solid satisfaction signal.

The bottom line: If you want the strongest mix of enthusiast appeal, year-round usability, and a market that still offers some deal opportunities, the 2018 is a sensible target. If you are especially price-sensitive, you may want to compare nearby years and focus on the cleanest, best-maintained example rather than chasing the lowest sticker price.
