How much does the 2017 Mercedes-Benz S-Class cost?

Prices have softened 5.94% compared to this time last year, making it a favorable time to shop this model year.

There are 700 listings available, which suggests you should have a reasonable amount of inventory to compare.

Is the 2017 Mercedes-Benz S-Class a good car?

Yes — the 4.9/5 user rating points to strong owner satisfaction. Owners consistently praise its elegant design, driving experience, performance, safety, and comfort, with the smooth handling and power standing out in particular. For you, that means this model year fits especially well if you want a high-end luxury car that emphasizes refinement and a polished driving experience. With 32.4% of listings marked as good or great deals, the market still offers some room to shop selectively.

Is the 2017 Mercedes-Benz S-Class reliable?

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

The owner feedback also describes it as dependable and luxurious, which supports the idea that many buyers feel confident living with it over time. That said, this is still a sophisticated flagship, so long-term ownership risk for used buyers is tied less to basic durability and more to the cost of repairs if a complex system needs attention.

What should I look for when buying a used 2017 Mercedes-Benz S-Class?

At 58.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and confirm whether any prior damage was repaired properly. A pre-purchase inspection should focus on the car’s electronics, suspension behavior, and signs of expensive wear, since this model’s complexity can make hidden issues costly. It also makes sense to prioritize overall condition and maintenance records over cosmetic appeal alone.

Is now a good time to buy a used 2017 Mercedes-Benz S-Class?

This looks like a moderate, selective buyer’s market, so you can shop carefully and still find worthwhile opportunities.

• Deal availability: 32.4% of listings are priced as good or great deals.
• Inventory: There are 700 listings available.
• Price trend: Prices have softened 5.94% compared with last year.
• Clean inventory: 58.3% of listings are accident-free.

If you find a listing below $38,268, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2017 Mercedes-Benz S-Class's resale value?

The current average of $38,359 sits slightly below last year's $40,783.

That price movement suggests the model has already absorbed some depreciation, which can help future sellers if they buy at the right price. If you purchase near the lower end of the range and keep the car in strong condition, you may be better positioned when it comes time to resell. Demand should remain supported by the model’s strong owner satisfaction and luxury 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 2017 Mercedes-Benz S-Class or consider a different year?

If you're weighing the 2017 against nearby model years, here's how to think about it:

Choose the 2017 if:

• 32.4% of listings are priced as good or great deals.
• At 58.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 5.94% compared with last year.
• Owners rate it 4.9/5 — a strong satisfaction signal.

The bottom line: The 2017 is the better path if you want this generation’s flagship luxury, strong owner approval, and a market that still offers some deal potential. If you are especially price-sensitive, a nearby year may be worth comparing, but the 2017 remains a compelling choice when you find a clean, well-kept example at the right price.
