At 50.2% 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 any prior damage was repaired properly. Then prioritize a pre-purchase inspection so you can check for signs of uneven wear, poor repairs, or lingering mechanical issues.

The current average of $12,868 sits slightly below last year's $13,238.

That softer pricing suggests the market has become a bit more buyer-friendly, which can make resale a little less aggressive in the near term. If you buy well and keep the car in strong condition, you may be better positioned to protect value when it’s time to sell.

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.
