At 51.6% 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 prior damage. After that, prioritize a pre-purchase inspection, especially if the listing price looks unusually attractive.

What is the 2018 Lexus IS's resale value?

The current average of $23,087 sits slightly below last year's $23,915.

That softer pricing suggests the market has become a bit more buyer-friendly, which can help you if you're shopping now but may limit upside if you're planning to sell soon. Even so, the model's steady appeal and compact luxury positioning can help support demand when you eventually list it. Well-kept examples with strong equipment and clean history should remain easier to move than neglected ones.

Vehicles with solid owner satisfaction ratings, like this model year's 4.29/5, tend to retain buyer demand, which supports resale value over time.
