How much does the 2018 Mercedes-Benz S-Class cost?

Prices have softened 9.99% compared to this time last year, making it a favorable time to shop this model year.

There are 741 listings available, which gives you a meaningful amount of inventory to compare.

Is the 2018 Mercedes-Benz S-Class a good car?

Yes — the 2018 Mercedes-Benz S-Class earns a 4.79/5 user rating, which points to strong owner satisfaction. Drivers consistently praise the luxurious interior, advanced technology, and smooth performance, and they also highlight the high-quality craftsmanship and spacious cabin. If you want a flagship luxury sedan with a polished, comfort-first feel, this model year fits that use case well. With 35.0% of listings marked as good or great deals, you have some room to shop selectively.

Is the 2018 Mercedes-Benz S-Class reliable?

Owners rate it 4.79/5, a strong signal of long-term satisfaction.

User feedback points to a car that feels dependable in daily use, with owners emphasizing its smooth performance and the kind of refined experience that encourages long-term ownership. The broader model-year description also notes a very good reliability record for the generation, even though upkeep can still be expensive. For used buyers, that means the bigger risk is often not basic durability but the cost of maintaining a sophisticated luxury sedan over time.

What should I look for when buying a used 2018 Mercedes-Benz S-Class?

At 64.1% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a full vehicle history report so you can separate clean examples from cars with prior damage. After that, prioritize a thorough pre-purchase inspection, especially on suspension, electrical, and other high-cost systems that can be expensive to sort out on a luxury sedan like this. Focus on overall condition and maintenance evidence, because a well-kept example is likely to be a much better ownership experience than a cheaper car with hidden issues.

Is now a good time to buy a used 2018 Mercedes-Benz S-Class?

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

• Deal availability: 35.0% of listings are priced as good or great deals.
• Inventory: There are 741 listings available.
• Price trend: Prices have softened 9.99% compared with last year.
• Clean inventory: 64.1% of listings are accident-free.

If you find a listing below $33,464, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2018 Mercedes-Benz S-Class's resale value?

The current average of $33,875 sits slightly below last year's $37,633.

That price movement suggests the market has already adjusted downward, which can help you buy at a more favorable entry point. If you plan to resell later, the current softness means your future value will depend heavily on how well you maintain the car and how clean its history is. Well-kept examples should remain easier to move than neglected ones, especially in a segment where buyers care a lot about condition and reputation.

Vehicles with strong owner satisfaction ratings, like this model year's 4.79/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2018 Mercedes-Benz S-Class or consider a different year?

If you're weighing the 2018 against nearby model years, here's how to think about it:

Choose the 2018 if:

• 35.0% of listings are priced as good or great deals.
• At 64.1% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 9.99% compared with last year.
• Owners rate it 4.79/5 — a strong satisfaction signal.

The bottom line: The 2018 is a strong choice if you want the S-Class experience at a softer price point and you’re willing to shop carefully for condition and history. If you’re especially price-sensitive, you may want to compare nearby years and focus on the cleanest, best-maintained example rather than chasing the lowest sticker price.
