How much does the 2020 Mercedes-Benz S-Class cost?

Prices have softened 11.17% compared to this time last year, making it a favorable time to shop this model year.

There are 602 listings available, which suggests you have a workable amount of inventory to compare.

If you find a listing below $46,807.77, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2020 Mercedes-Benz S-Class a good car?

Yes — the 2020 Mercedes-Benz S-Class earns a 4.9/5 user rating, which points to very strong owner satisfaction.

Owners consistently praise the luxurious feel, the impressive performance, and the advanced features. The comfort of the ride is another recurring strength, and that fits a car built to serve as a flagship luxury sedan with technology and engineering at the center of the experience.

If you want a sedan that emphasizes comfort, high-end tech, and strong power, this model year fits that use case well. The market also shows 30.6% of listings as good or great deals, which gives you some room to shop selectively.

Is the 2020 Mercedes-Benz S-Class reliable?

Owners rate it 4.9/5, a strong signal of long-term satisfaction.

The owner feedback also points to a dependable ownership experience in the sense that many drivers feel confident in the car’s comfort, performance, and overall quality over time. That said, some owners note that maintenance costs can be high, so long-term ownership risk is less about basic satisfaction and more about keeping up with premium upkeep.

What should I look for when buying a used 2020 Mercedes-Benz S-Class?

At 73.3% 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 thorough pre-purchase inspection, especially on a luxury sedan where repair costs can escalate quickly.

Focus your condition check on signs of past bodywork, uneven panel gaps, and any evidence of deferred maintenance. Because this model is expensive to own, the best used example is usually the one with the cleanest history and the most consistent service record.

Is now a good time to buy a used 2020 Mercedes-Benz S-Class?

This looks like a moderate, selective buyer’s market, so you can shop carefully without expecting every listing to be a bargain.

• Deal availability: 30.6% of listings are priced as good or great deals.
• Inventory: There are 602 listings available.
• Price trend: Prices have softened 11.17% compared with last year.
• Clean inventory: 73.3% of listings are accident-free.

If you find a listing below $46,807.77, that's toward the low end of the year-round range and worth acting on quickly.

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

The current average of $47,605 sits slightly below last year's $53,590.

That decline suggests the market has already adjusted downward, which can help you as a buyer but may limit upside if you plan to resell soon. For a future seller, the key takeaway is that pricing discipline matters: buying well now gives you a better chance of protecting value later.

Strong owner satisfaction can help support demand when it is time to sell, especially for a flagship luxury sedan with broad appeal. Vehicles with strong owner satisfaction ratings, like this model year's 4.9/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2020 Mercedes-Benz S-Class 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:

• 30.6% of listings are priced as good or great deals.
• At 73.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 11.17% compared with last year.
• Owners rate it 4.9/5 — a strong satisfaction signal.

Consider the 2021 if:

• At $59,567, the 2021 costs more than the current year's $47,605 average.
• It brings a redesigned flagship with more sophisticated infotainment and updated powertrains.

The bottom line: If you want the better value play, the 2020 is the stronger starting point because pricing has eased and inventory is available. If you’re willing to pay more for the newer redesign and updated tech, the 2021 is the better secondary path for buyers who prioritize the latest version over savings.
