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

Prices have softened 6.54% compared to this time last year, making it a favorable time to shop this model year.

There are 345 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 is the last version of the original design before the model was completely redesigned for 2019. It keeps the boxy, rugged character that made the G-Class famous, while also adding enough modern equipment to work as a daily driver.

What makes it especially appealing is the mix of old-school toughness and luxury. You get the classic G-Wagen look and feel, serious off-road capability, and a cabin that had already been updated with modern convenience and driver-assist features.

For you, that means this model makes the most sense if you want iconic style and real capability in one package. 34.2% of listings are priced as good or great deals, which 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 expensive maintenance and repair costs because the truck is full of costly hardware. That makes it a strong fit if you value durability and can accept premium ownership expenses.

For used buyers, the long-term risk is less about basic dependability and more about the cost of keeping the vehicle in top condition over time.

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

At 72.2% 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 confirm accident records, title status, and service history before you get too far into the process. After that, prioritize a thorough pre-purchase inspection, especially on a vehicle where repairs can be expensive. Focus on overall condition, because with this model, cosmetic wear and deferred maintenance can quickly become costly.

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

This is a moderate market, so you can shop selectively without expecting a deep buyer’s market.

• Deal availability: 34.2% of listings are priced as good or great deals.
• Inventory: There are 345 listings available.
• Price trend: Prices have softened 6.54% compared with last year.
• Clean inventory: 72.2% of listings are accident-free.

If you find a listing below $80,517, 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 $81,893 sits slightly below last year's $87,620.

That decline suggests the market has cooled compared with a year ago, which can make the vehicle more attractive to you as a buyer. For a future seller, it means pricing may need to stay competitive if you want to move the vehicle quickly. The current trend still supports strong value retention relative to many luxury SUVs, but the direction is softer than it was last year.

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:

• 34.2% of listings are priced as good or great deals.
• At 72.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 6.54% compared with last year.

Consider the 2019 if:

• At $105,185, the 2019 costs more than the current year's $81,893 average.
• It brings a full redesign with a much more modern interior.

The bottom line: If you want the classic G-Class shape and a lower entry price, the 2018 is the smarter primary path. If you are willing to pay significantly more for the redesigned look and a more modern cabin, the 2019 is the better secondary path.
