You should run a vehicle history report on every candidate and prioritize listings with clean records.

What is the 2020 Lexus IS's resale value?

The current average of $27,592 sits slightly below last year's $27,899.

That small decline suggests the market has eased a bit, which can help you buy at a more favorable entry point today.

Well-kept examples should still hold appeal because the model has a clear enthusiast-friendly identity and a strong value proposition in the compact luxury segment.

Vehicles with strong owner satisfaction ratings, like this model year's 4.5/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2020 Lexus IS or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 34.0% of listings are priced as good or great deals.
• At 66.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 1.10% compared with last year.
• Owners rate it 4.5/5 — a strong satisfaction signal.

Consider the 2021 if:

• At $34,672, the 2021 costs more than the current year's $27,592 average.
• It brings a sharper fourth-generation redesign with more modern styling and a stronger enthusiast focus.

The bottom line: If you want the better value, the 2020 is the smarter starting point because it combines a lower average price with decent deal availability. If you’re willing to pay more for a newer-generation feel and a more aggressive design direction, the 2021 is the better upgrade path.
