Focus on overall condition, maintenance consistency, and evidence of careful ownership rather than just mileage alone.

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:

• 24.1% of listings are priced as good or great deals.
• At 60.9% 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 current pricing stability, enthusiast appeal, and owner satisfaction, the 2018 is a sensible place to focus. If you are especially price-sensitive, you can also compare nearby years to see whether a cleaner or cheaper example better fits your budget, but you should still prioritize condition and history over small differences in asking price.
