What is the 2020 Mercedes-Benz CLS's resale value?

The current average of $33,444 sits slightly below last year's $37,908.

That price movement suggests the market has cooled, which can help you buy at a more favorable entry point today.

Well-kept examples should hold up better than average listings in a market like this.

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:

• 35.9% of listings are priced as good or great deals.
• At 67.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 11.78% compared with last year.

Consider the 2019 if:

• At $30,341, the 2019 costs less than the current year's $33,444 average.
• It stands out for striking styling.

The bottom line: If you want the newer year and are comfortable shopping carefully, the 2020 is the better primary target because pricing has eased and deal availability is solid. If your priority is spending less upfront, the 2019 is the stronger value path, especially if you find a clean example with good documentation.
