When it comes to depreciation, most luxury vehicles take a steep dive in their first few years. But the 2018 Mercedes Benz G63 AMG defies the norm. Thanks to its iconic status, limited production, and high demand, this model retains a significant portion of its original value. According to industry data from Kelley Blue Book and Edmunds, the G63 AMG typically holds 60–70% of its MSRP after three years—far outperforming competitors like the Range Rover Sport or BMW X5 M.
Several factors contribute to this impressive resale strength. First, the G-Class has one of the most loyal fan bases in the automotive world. Enthusiasts and collectors prize its heritage, and the AMG badge adds a layer of exclusivity. Second, production numbers are relatively low compared to mainstream SUVs, creating a sense of scarcity. Finally, the 2018 model benefits from being part of the final generation before the complete redesign in 2019, making it a bridge between classic and modern G-Wagens.
For buyers, this means two things: if you’re purchasing used, you’re getting a well-preserved, high-demand vehicle. If you’re selling, you can expect a strong return on your investment. Even in today’s market, a well-maintained 2018 G63 AMG with low mileage can fetch $90,000 to $110,000, depending on condition, options, and location.
Market Trends and Demand
The used luxury SUV market has seen fluctuations in recent years, but the G63 AMG has remained resilient. While electric vehicles and newer models grab headlines, the G63’s blend of analog charm and digital sophistication keeps it relevant. In fact, demand has grown among younger buyers who appreciate its retro-modern aesthetic and social media appeal.
Online marketplaces like Autotrader, Cars.com, and even Instagram show consistent interest in the 2018 model. Search volume for “2018 Mercedes G63 AMG value” has increased by over 25% in the past two years, according to Google Trends. This sustained interest helps maintain pricing stability and reduces the risk of sudden depreciation.
Factors That Influence Resale Value
Not all 2018 G63 AMGs are created equal when it comes to value. Several key factors can significantly impact how much your vehicle is worth:
- Mileage: Lower mileage (under 30,000 miles) commands a premium. Vehicles with over 60,000 miles see a noticeable drop in price.
- Service History: A complete maintenance record from a Mercedes-Benz dealership or certified mechanic adds credibility and value.
- Accident History: Clean title vehicles with no reported accidents are far more desirable. Even minor fender benders can reduce value by 10–15%.
- Options and Packages: Models with the AMG Performance Studio Package, Designo leather, or carbon fiber trim tend to sell for more.
- Color: Classic colors like black, white, and silver hold value better than bold hues like red or matte finishes.
- Location: Urban markets with high disposable income (e.g., Los Angeles, Miami, New York) often see higher resale prices.
Performance and Driving Dynamics
Under the hood of the 2018 G63 AMG lies a beast—a hand-built 5.5-liter twin-turbocharged V8 engine that produces 563 horsepower and 561 lb-ft of torque. This power is channeled through a 7-speed automatic transmission and permanent all-wheel drive, delivering acceleration that feels more like a sports car than a 5,000-pound SUV. The 0–60 mph sprint takes just 5.3 seconds, which is faster than many modern supercars from the early 2000s.
But the G63 AMG isn’t just about straight-line speed. Its adaptive suspension system, developed in partnership with AMG, offers multiple driving modes—Comfort, Sport, Sport+, and Individual—allowing drivers to tailor the ride to their preferences. In Comfort mode, the ride is surprisingly smooth for such a rugged vehicle, absorbing bumps with ease. Switch to Sport+, and the suspension firms up, the exhaust note deepens, and the throttle response becomes razor-sharp.
Off-Road Capability
Despite its luxury trappings, the G63 AMG is no slouch when the pavement ends. It retains the G-Class’s legendary off-road DNA, including:
- Three Locking Differentials: Front, center, and rear differentials can be locked manually for maximum traction on loose or uneven terrain.
- Low-Range Transfer Case: Provides extra torque for climbing steep inclines or navigating rocky trails.
- Adaptive Damping System: Automatically adjusts shock absorber firmness based on terrain and driving style.
- High Ground Clearance: With 9.5 inches of clearance, it can handle deep ruts, logs, and water crossings with confidence.
We tested a 2018 G63 AMG on a desert trail in Arizona, and it handled sand dunes, rock crawls, and muddy patches with ease. The only limitation? Its size. At nearly 19 feet long and over 6.5 feet wide, tight trails can be challenging. But for open terrain, it’s in its element.
On-Road Refinement
On the highway, the G63 AMG surprises with its composure. The cabin is well-insulated against wind and road noise, and the adaptive suspension keeps body roll in check during cornering. The steering is direct and communicative, a rarity in large SUVs. However, it’s not without quirks. The tall, boxy shape creates noticeable wind noise at high speeds, and the ride can feel stiff in Sport mode over rough pavement.
Fuel economy is another consideration. The EPA rates the G63 AMG at 12 mpg city and 15 mpg highway, which is typical for a high-performance SUV of this size. In real-world driving, expect around 13–14 mpg combined. With a 26.4-gallon fuel tank, range is decent, but frequent fill-ups are part of the ownership experience.
Interior Luxury and Technology
Step inside the 2018 G63 AMG, and you’re greeted by a cabin that blends old-school charm with cutting-edge tech. The dashboard features a dual-screen setup—two 12.3-inch displays that serve as the digital instrument cluster and infotainment center. This was a major upgrade from earlier models and brought the G-Class into the modern era.
Materials are top-tier. Standard features include Nappa leather upholstery, hand-polished wood trim, and aluminum pedals. Optional upgrades include Designo semi-aniline leather, carbon fiber accents, and a panoramic sunroof. The seats are power-adjustable with memory settings, heating, and ventilation—perfect for long drives or cold mornings.
Infotainment and Connectivity
The COMAND infotainment system, while not as intuitive as newer MBUX systems, is functional and responsive. It includes:
- Navigation with real-time traffic updates
- Bluetooth audio and phone connectivity
- Apple CarPlay (via USB, not wireless)
- Harman Kardon premium audio system (standard)
- Optional Burmester 3D surround sound
The interface relies on a central knob and touchpad, which takes some getting used to. Voice commands are available but limited. For 2018, it’s a solid system, though newer models offer more seamless integration.
Comfort and Practicality
Despite its rugged exterior, the G63 AMG is surprisingly comfortable for daily use. The front seats offer excellent support, and the rear seats provide ample legroom for adults. Cargo space is generous—36.8 cubic feet behind the second row, expanding to 74.9 cubic feet with the seats folded. That’s more than enough for luggage, golf clubs, or camping gear.
Climate control is dual-zone up front, with optional rear vents. The ambient lighting system offers 64 colors, adding a futuristic touch to the cabin. Storage is plentiful, with deep door pockets, a large center console, and cup holders that can accommodate large water bottles.
One minor gripe? The rear visibility is limited due to the thick C-pillars and small rear window. A rearview camera helps, but it’s not a substitute for good sightlines.
Ownership Costs and Maintenance
Owning a 2018 Mercedes Benz G63 AMG is a privilege—but it comes with a price tag beyond the purchase. Maintenance, fuel, insurance, and repairs can add up quickly, especially compared to mainstream SUVs.
Routine Maintenance
Mercedes-Benz recommends service every 10,000 miles or once a year, whichever comes first. A typical A-Service (oil change, filter, inspection) costs around $400–$600 at a dealership. B-Service, which includes more extensive checks, runs $800–$1,200. Independent shops may offer lower rates, but using non-dealer parts can affect warranty coverage and resale value.
Tires are another expense. The G63 AMG comes with 20-inch or 21-inch wheels and high-performance tires that wear faster than standard all-seasons. A full set can cost $1,500–$2,500, depending on brand and size.
Repairs and Reliability
The 2018 G63 AMG is generally reliable, but it’s not immune to issues. Common problems reported by owners include:
- Air Suspension Leaks: The adaptive air suspension can develop leaks over time, leading to a sagging ride. Repairs can cost $1,500–$3,000.
- Electrical Glitches: Infotainment freezes, sensor malfunctions, and warning lights are occasional complaints. Software updates often resolve these.
- Brake Wear: The heavy vehicle and powerful engine lead to faster brake pad and rotor wear. Front brake service can cost $800–$1,200.
- Turbo Issues: While rare, turbocharger failures have been reported in high-mileage examples. Early signs include reduced power and unusual noises.
Extended warranties or prepaid maintenance plans can help mitigate these costs. Many owners opt for third-party coverage to avoid dealership markups.
Insurance and Depreciation
Insurance premiums for the G63 AMG are high due to its value, performance, and repair costs. Expect to pay $2,500–$4,000 annually for full coverage, depending on location and driving history. Comprehensive and collision coverage are essential given the vehicle’s value.
Depreciation, while slower than average, still occurs. After five years, a 2018 G63 AMG may be worth 50–60% of its original price. However, well-maintained examples with low mileage can defy this trend, especially in strong markets.
Is the 2018 G63 AMG a Good Buy in 2024?
With the 2024 model year now available, is the 2018 G63 AMG still a smart purchase? The answer is a resounding yes—for the right buyer.
Pros of Buying Used
- Lower Entry Price: A used 2018 model costs $20,000–$40,000 less than a new one, depending on mileage and condition.
- Proven Reliability: Eight years of real-world use have revealed common issues, making it easier to inspect and avoid problem vehicles.
- Same Core Experience: The driving dynamics, design, and performance are nearly identical to newer models.
- Strong Resale: As discussed, it holds value well, so you’re less likely to lose money if you decide to sell later.
Cons to Consider
- Outdated Tech: The COMAND system lacks wireless Apple CarPlay, over-the-air updates, and the latest driver aids.
- Higher Maintenance Risk: Older vehicles are more prone to wear and tear, especially if maintenance was neglected.
- No Warranty: Most 2018 models are out of factory warranty, so repairs are out-of-pocket unless covered by an extended plan.
Tips for Buyers
If you’re considering a 2018 G63 AMG, follow these tips:
- Get a Pre-Purchase Inspection (PPI): Have a certified Mercedes technician inspect the vehicle, focusing on the suspension, engine, and electronics.
- Check Service Records: Look for consistent maintenance, especially oil changes and brake services.
- Test Drive on Different Surfaces: Evaluate how it handles on highways, city streets, and rough roads.
- Negotiate Based on Condition: Use any flaws or needed repairs as leverage to lower the price.
- Consider a CPO Program: Some dealers offer certified pre-owned G63 AMGs with extended warranties and inspections.
