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.

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-feeling experience, with praise centered on comfort, advanced features, and the kind of ownership confidence that comes from a well-liked luxury sedan. At the same time, some drivers note that maintenance costs can be high, so long-term ownership risk is less about day-to-day satisfaction and more about budgeting for premium upkeep.

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

At 73.4% 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 escalate quickly if something has been overlooked. Focus on overall condition, maintenance evidence, and signs of expensive wear rather than just the odometer reading.

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

The current average of $48,596 sits slightly below last year's $55,366.

That decline suggests the market has already adjusted downward, which can help you as a buyer today but may temper future resale gains if you purchase at the wrong price. For a future seller, the key is to buy well and keep the car in excellent condition, because luxury sedans tend to reward clean history and strong presentation more than average examples. The model’s strong owner satisfaction should help support demand over time.

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:

• 32.7% of listings are priced as good or great deals.
• At 73.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 12.23% compared with last year.
• Owners rate it 4.9/5 — a strong satisfaction signal.

Consider the 2021 if:

• At $60,793, the 2021 costs more than the current year's $48,596 average.
• It brings a redesigned cabin with more advanced tech 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 owner satisfaction is excellent. If you’re willing to spend more for the newer redesign and updated technology, the 2021 is the better secondary path for buyers who prioritize the latest features over price.
