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

Prices are up 3.55% year-over-year — a sign of continued demand for this model year.

There are 339 listings available, which gives you a modest amount of inventory to compare before you buy.

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

The 2018 Mercedes-Benz G-Class stands out because it keeps the classic boxy G-Wagen identity intact while pairing it with a refreshed cabin and modern convenience features. For you, that means this model year offers the familiar rugged character and status-symbol appeal of the original design, along with updated tech and driver-assist equipment that make it feel more usable day to day. It is especially compelling if you want a luxury SUV with serious off-road credibility and a distinctive presence.

The market shows 31.9% of listings as good or great deals, which suggests there are still some attractive opportunities if you shop carefully.

Is the 2018 Mercedes-Benz G-Class reliable?

The 2018 Mercedes-Benz G-Class is described as a long-running design that had already been refreshed over the years, which points to a familiar formula rather than a brand-new platform. It also carries the kind of rugged character that helped make the G-Class famous in the first place, while adding modern cabin and driver-assist updates.

For used buyers, long-term ownership risk is tied more to expensive upkeep and the cost of keeping a premium, specialized SUV in top condition than to simple day-to-day use.

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

At 70.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should run a vehicle history report on any candidate you are serious about and prioritize a pre-purchase inspection from a shop that knows luxury SUVs. Focus on body condition, signs of prior repair, and whether the cabin and electronics show the wear you would expect from a high-priced, heavily used vehicle.

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

This looks like a moderate, selective buyer's market: there is inventory to choose from, but the best examples still deserve quick attention.

• Deal availability: 31.9% of listings are priced as good or great deals.
• Inventory: There are 339 listings available.
• Price trend: Prices are up 3.55% year-over-year.
• Clean inventory: 70.5% of listings are accident-free.

If you find a listing below $80,558, that's toward the low end of the year-round range and worth acting on quickly.

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

The current average of $85,989 sits slightly above last year's $83,044.

That upward move suggests the market has held value reasonably well for this model year. If you sell, you may benefit from the G-Class's strong identity and continued demand, especially if your vehicle has clean history and strong presentation. Well-kept examples should remain easier to position than neglected ones because buyers in this segment tend to pay for condition and provenance.

Should I buy a 2018 Mercedes-Benz G-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:

• 31.9% of listings are priced as good or great deals.
• At 70.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices are up 3.55% year-over-year.

Consider the 2019 if:

• At $105,792, the 2019 costs more than the current year's $85,989 average.
• It brings a fully redesigned cabin with stronger modern luxury appeal.

The bottom line:
Choose the 2018 if you want the classic G-Class look and a lower entry price. If you are more focused on the newest design and can stretch your budget, the 2019 is the better upgrade path. For price-sensitive buyers, the 2018 remains the more approachable way to get into the G-Class nameplate.
