How much does the 2023 Mercedes-Benz G-Class cost?

Prices have softened 2.43% compared to this time last year, making it a favorable time to shop this model year.

There are 831 listings available, which suggests you have a meaningful amount of inventory to compare.

If you find a listing below $171,402.87, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2023 Mercedes-Benz G-Class a good car?

The 2023 Mercedes-Benz G-Class stands out because it blends an unmistakable military-grade shape with the kind of luxury and technology buyers expect from a modern Mercedes. Its appeal is rooted in that contrast: the SUV still looks like a rugged off-roader, but it was completely redesigned in 2019 as a luxury off-road machine with modern systems, lightweight structural materials, and a much plusher interior.

It also uses Mercedes-Benz MBUX infotainment on a flat-panel dashboard with two 12.3-inch displays, and it adds driver-assist and safety features developed for other Mercedes models. For you, that means the G-Class makes the most sense if you want iconic styling, strong power, and genuine off-road capability in one package.

Market availability: 27.7% of listings are priced as good or great deals.

Is the 2023 Mercedes-Benz G-Class reliable?

The 2023 Mercedes-Benz G-Class is presented as a high-end SUV with serious capability, but it is also expensive to buy and maintain. Its limited production means used examples can be hard to find, which can make shopping more selective and ownership planning more important.

For used buyers, that means long-term ownership risk is tied less to everyday simplicity and more to the cost of keeping a complex luxury SUV in top condition.

What should I look for when buying a used 2023 Mercedes-Benz G-Class?

Accident-free inventory is excellent at 92.8% — clean inventory, standard diligence applies.

You should still run a history report on any candidate and prioritize a pre-purchase inspection, especially because this is a high-value luxury SUV with complex systems. Focus on overall condition, maintenance records, and signs of hard use, since the G-Class can attract buyers who use it very differently from a typical SUV.

Is now a good time to buy a used 2023 Mercedes-Benz G-Class?

This is a moderate market, so you can be selective without assuming every listing is a bargain.

• Deal availability: 27.7% of listings are priced as good or great deals.
• Inventory: There are 831 listings available.
• Price trend: Prices have softened 2.43% compared with last year.
• Clean inventory: 92.8% of listings are accident-free.

If you find a listing below $171,402.87, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2023 Mercedes-Benz G-Class's resale value?

The current average of $173,560 sits slightly below last year's $177,879.

That price movement suggests the market has eased a bit, which can help you buy with less pressure today. For a future seller, it also means resale value may remain strong in absolute terms, but you should not expect rapid appreciation from current levels. If you buy well and keep the vehicle in excellent condition, you give yourself the best chance of protecting value later.

Should I buy a 2023 Mercedes-Benz G-Class or consider a different year?

If you're weighing the 2023 against nearby model years, here's how to think about it:

Choose the 2023 if:

• 27.7% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 92.8% — clean inventory, standard diligence applies.
• Price trend: Prices have softened 2.43% compared with last year.

The bottom line: The 2023 is a strong choice if you want the classic G-Class look with modern luxury and you value current-market pricing that has eased a bit. If you are more price-sensitive, a nearby model year may be worth comparing, but the 2023 gives you a good balance of inventory, condition, and market softness.
