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

Prices have softened 8.27% compared to this time last year, making it a favorable time to shop this model year.

There are 357 listings available, which gives you a meaningful amount of inventory to compare.

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 boxy, rugged character, a refreshed cabin, an iPad-like infotainment screen, internet connectivity, and driver-assist features such as adaptive cruise control, blind spot monitoring, and collision avoidance systems.

For you, that means the 2018 G-Class makes the most 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 image. 32.2% 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 high maintenance and repair costs because the truck is full of expensive gear. That makes it appealing if you want a durable, well-built SUV with serious off-road hardware, including four-wheel drive with electronic locking front, center, and rear differentials.

For used buyers, the long-term ownership risk is less about whether it can last and more about how costly it can be to keep in top condition.

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

At 72.5% 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 and prioritize a pre-purchase inspection from a shop that knows luxury SUVs. Focus on overall condition, signs of prior bodywork, and whether the expensive equipment and off-road hardware have been maintained properly.

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 expecting every listing to be a bargain.

• Deal availability: 32.2% of listings are priced as good or great deals.
• Inventory: There are 357 listings available.
• Price trend: Prices have softened 8.27% compared with last year.
• Clean inventory: 72.5% 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 $81,219 sits slightly below last year's $88,545.

That tells you the market has moved down from where it was a year ago, which can help you as a buyer but may temper short-term resale expectations if you plan to sell soon. If you buy well, the G-Class still has strong desirability, but the current pricing trend suggests you should be realistic about near-term appreciation. For a future seller, condition and history will matter a lot when it comes time to list.

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:

• 32.2% of listings are priced as good or great deals.
• At 72.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 8.27% compared with last year.

Consider the 2019 if:

• At $105,414, the 2019 costs more than the current year's $81,219 average.
• The redesign brings a much more modern cabin and broader everyday appeal.

The bottom line: If you want the classic G-Class shape and a lower entry price, the 2018 is the smarter primary choice. If you are willing to spend more for the redesigned model’s newer feel and broader appeal, the 2019 is the better upgrade path. For price-sensitive buyers, the 2018 gives you the iconic look with a much lower average cost.
