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

Prices have softened 2.75% compared to this time last year, making it a favorable time to shop this model year.

There are 350 listings available, which gives you a meaningful pool to compare prices and conditions.

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

The 2018 Mercedes-Benz G-Class stands out because it is the last version of the original design before the model was completely redesigned for 2019. It combines old-school toughness and luxury, with a refreshed cabin, modern infotainment, driver-assist features, and serious off-road hardware.

For you, that means this model year makes sense if you want the classic G-Wagen look and feel with enough modern equipment to use every day. It also remains one of the most expensive SUVs in Mercedes-Benz’s lineup, so you are paying for both capability and status.

With 34.3% of listings marked as good or great deals, the market gives you some room to shop selectively.

Is the 2018 Mercedes-Benz G-Class reliable?

The 2018 Mercedes-Benz G-Class is described as generally very reliable, but it also comes with high maintenance and repair costs because the truck is packed with expensive hardware. That makes it appealing if you value durability and character, but less forgiving if you want low-cost ownership.

For used buyers, the long-term risk is not so much frequent breakdowns as expensive upkeep when wear items or repairs do come due.

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

At 74% 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 cosmetic or structural. Then prioritize a pre-purchase inspection that focuses on the drivetrain, suspension, electronics, and signs of deferred maintenance. Because this is an expensive SUV to own, condition matters as much as mileage.

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

This looks like a moderate, selective buyer's market, so you can shop carefully without feeling rushed.

• Deal availability: 34.3% of listings are priced as good or great deals.
• Inventory: There are 350 listings available.
• Price trend: Prices have softened 2.75% compared with last year.
• Clean inventory: 74.0% of listings are accident-free.

If you find a listing below $80,505, 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 $84,087 sits slightly below last year's $86,461.

That softer pricing can help you buy more carefully today, but it also suggests the market has already adjusted downward from prior levels. If you plan to sell later, your resale outcome will depend heavily on condition, mileage, and maintenance history. Well-kept examples should hold appeal because the G-Class has strong image value, but expensive ownership can narrow the buyer pool.

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:

• 34.3% of listings are priced as good or great deals.
• At 74% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 2.75% compared with last year.

Consider the 2019 if:

• At $104,650, the 2019 costs more than the current year's $84,087 average.
• The redesign brings a far more modern feel and a more polished interior.

The bottom line: If you want the classic shape and a lower entry price, the 2018 is the smarter primary path. If you are willing to spend more for the redesigned look and a more modern cabin, the 2019 is the better upgrade; price-sensitive buyers should stay focused on the 2018.
