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:

• 33.7% of listings are priced as good or great deals.
• At 66.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 10.72% compared with last year.

Consider the 2019 if:

• At $31,037, the 2019 costs less than the current year's $34,385 average.
• It stands out for styling and a refined luxury feel.

The bottom line: Choose the 2020 if you want the newer year with a softer market and a decent pool of listings to compare. If you are more price-sensitive, the 2019 is the better path because it undercuts the current year while still offering the CLS's standout design and premium character.
