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

Prices have softened 7.94% compared to this time last year, making it a favorable time to shop this model year.

There are 677 listings available, which gives you a solid pool of options to compare.

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

Yes — the 4.8/5 user rating points to strong owner satisfaction. Drivers consistently praise the luxurious interior, advanced technology, smooth performance, high-quality craftsmanship, and spacious cabin, which fits well if you want a flagship luxury sedan with a quiet, opulent feel and a strong mix of comfort and performance. With 34.7% of listings marked as good or great deals, you also have a decent chance of finding a competitive price.

Is the 2018 Mercedes-Benz S-Class reliable?

Owners rate it 4.8/5, a strong signal of long-term satisfaction.

The user feedback points to a car that feels refined, dependable, and well built over time, with owners especially appreciating the craftsmanship and smooth driving experience. For used buyers, the main long-term ownership risk is less about day-to-day satisfaction and more about the cost and complexity that can come with keeping a flagship luxury sedan in top shape.

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

At 64.4% 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 prior damage or repeated claims. After that, prioritize a thorough pre-purchase inspection, especially on a luxury sedan where repairs can be expensive if hidden issues show up later. Focus your condition check on signs of wear, uneven panel fit, and anything that suggests the car may have been used hard or repaired poorly.

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 opportunities.

• Deal availability: 34.7% of listings are priced as good or great deals.
• Inventory: There are 677 listings available.
• Price trend: Prices have softened 7.94% compared with last year.
• Clean inventory: 64.4% of listings are accident-free.

If you find a listing below $33,605, 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 $34,107 sits slightly below last year's $37,049.

That price movement suggests the market has already adjusted downward, which can help you buy more confidently now but may also limit short-term upside if you plan to resell soon. For a future seller, the key is to buy well and keep the car in excellent condition, because a luxury sedan's resale value depends heavily on how cleanly it presents and how well it has been maintained. Vehicles with strong owner satisfaction ratings, like this model year's 4.8/5, 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:

• 34.7% of listings are priced as good or great deals.
• At 64.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 7.94% compared with last year.
• Owners rate it 4.8/5 — a strong satisfaction signal.

The bottom line: You should lean toward the 2018 if you want a well-liked flagship luxury sedan with strong owner satisfaction and a softer used-car price than it had a year ago. If you're especially price-sensitive, a nearby model year may be worth comparing, but the 2018 remains a compelling choice when you find a clean, well-priced example.
