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

Prices have softened 12.39% compared to this time last year, making it a favorable time to shop this model year.

There are 615 listings available, which gives you a solid pool to compare prices and equipment.

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 its luxurious feel, impressive performance, and comfort-focused ride. They also highlight the advanced features, which fit well if you want a flagship sedan that emphasizes technology and refinement. The overview also frames it as a high-end luxury sedan with serious performance, so it suits you best if you value comfort, prestige, and a deeply equipped cabin.

With 33.0% of listings marked as good or great deals, you have a meaningful number of opportunities to find a competitive price.

Is the 2020 Mercedes-Benz S-Class reliable?

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

The owner feedback points to a car that feels luxurious and impressive to live with, and it also reflects the kind of confidence that comes from a well-liked flagship sedan. The reliability discussion also emphasizes that the generation’s record is very good overall, which supports the idea that many owners have had a positive long-term experience.

For used buyers, the main ownership risk is not just whether the car runs well today, but whether you can absorb potentially expensive maintenance over time.

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

At 73% 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. Then prioritize a pre-purchase inspection, especially if the car has complex electronics, suspension components, or signs of heavy use. Focus your condition check on maintenance records, interior wear, and any warning lights or uneven ride behavior.

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

This is a selective buyer’s market, so you can be choosy if you’re patient and compare listings carefully.

• Deal availability: 33.0% of listings are priced as good or great deals.
• Inventory: There are 615 listings available.
• Price trend: Prices have softened 12.39% compared with last year.
• Clean inventory: 73.0% of listings are accident-free.

If you find a listing below $46,617, 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 $46,617 sits slightly below last year's $53,207.

That decline suggests the market has already adjusted downward, which can help you buy more confidently now but may also limit near-term upside if you plan to resell soon. For a future seller, the key takeaway is that value retention will depend heavily on condition, mileage, and how well the car has been maintained. A clean history and strong presentation matter even more when the market is already softer.

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:

• 33.0% of listings are priced as good or great deals.
• At 73% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 12.39% compared with last year.
• Owners rate it 4.9/5 — a strong satisfaction signal.

Consider the 2021 if:

• At $59,063, the 2021 costs more than the current year's $46,617 average.
• It brings a redesigned cabin with newer tech and updated powertrains.

The bottom line: If you want the better value play, the 2020 is the stronger starting point because it combines a lower average price with solid owner satisfaction and meaningful deal availability. If you’re willing to spend more for a newer redesign and updated technology, the 2021 is the better upgrade path; if price matters most, stay focused on the 2020 and shop carefully for a clean, well-kept example.
