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

Prices have softened 9.29% compared to this time last year, making it a favorable time to shop this model year.

There are 578 listings available, which gives you a solid pool of options to compare.

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, impressive performance, comfort of the ride, and advanced features. That lines up well if you want a flagship luxury sedan that emphasizes technology and refinement, while still delivering serious performance. The tradeoff is that upkeep can be expensive, so it fits best if you value premium comfort and features enough to accept higher ownership costs.

With 33.7% of listings marked as good or great deals, you have 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 points to a car that feels luxurious, comfortable, and impressive to live with over time. The recurring praise for the ride and features suggests many buyers find it dependable in day-to-day use, even if ownership costs can be high.

For used buyers, the main long-term risk is less about basic appeal and more about expensive maintenance if the car has been neglected.

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

At 72.3% 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 accident records. After that, prioritize a thorough pre-purchase inspection, especially on a luxury sedan where repair costs can climb quickly. Focus on overall condition, maintenance history, and signs of deferred upkeep, since those factors matter more than mileage alone on a car like this.

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

This is a moderate, selective buyer’s market, so you can shop carefully and still find worthwhile listings.

• Deal availability: 33.7% of listings are priced as good or great deals.
• Inventory: There are 578 listings available.
• Price trend: Prices have softened 9.29% compared with last year.
• Clean inventory: 72.3% of listings are accident-free.

If you find a listing below $45,742, 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 $46,076 sits slightly below last year's $50,794.

That price movement suggests the market has already adjusted downward, which can help you buy at a better entry point now. For a future seller, it also means resale value may depend heavily on condition, mileage, and service history rather than just the badge alone. Well-kept examples should hold up better than neglected ones, especially in a segment where buyers expect premium presentation.

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:

• 33.7% of listings are priced as good or great deals.
• At 72.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 9.29% compared with last year.
• Owners rate it 4.9/5 — a strong satisfaction signal.

Consider the 2021 if:

• At $58,069, the 2021 costs more than the current year's $46,076 average.
• It brings a redesigned cabin and updated technology.

The 2020 is the better primary choice if you want a lower entry price and strong owner satisfaction. If you’re price-sensitive, it’s the smarter path; if you want the newer redesign and can stretch your budget, the 2021 is worth a look.
