Should I buy a 2020 Mercedes-Benz CLS 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:

• 32.9% of listings are priced as good or great deals.
• At 68.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 12.22% compared with last year.

Consider the 2019 if:

• At $30,178, the 2019 costs less than the current year's $32,847 average.
• The 2019 emphasizes striking styling and a more advanced luxury feel.

The bottom line: Choose the 2020 if you want the current-year market with decent deal availability and are willing to shop carefully for condition. If you’re more price-sensitive, the 2019 is the better path because it costs less while still leaning hard into the CLS’s style-first appeal.
