The 2004 Mercedes-Benz G-Class, also known as the G-Wagen, boasts a rugged and iconic history rooted in military applications. This SUV features a boxy, instantly recognizable body style. Key trims include the G500. Originally produced from 1979 and continuously evolving, it's popular for its off-road prowess, luxurious appointments, and status symbol appeal. Pricing in 2004 ranged considerably, and used models today vary significantly. Its enduring design and go-anywhere capability are major draws.
The Good

The 2004 G-Class offers robust off-road performance, a comfortable and luxurious interior, and iconic, head-turning design. For practical buyers, its durability and all-weather capability are appealing. Emotionally, its exclusivity and status make it desirable. Reliability can be good with proper maintenance, but it's not its strongest suit. Fuel efficiency is notably poor.

The Bad

The 2004 G-Class has several weaknesses. Fuel economy is abysmal. Handling can be cumbersome on pavement. Repair costs are high due to its complex systems and relatively low production numbers. Watch out for rust, particularly in areas prone to salt exposure. Electrical issues and transfer case problems are also potential concerns.

2004 Mercedes-Benz G-Class: Quick Overview

  • Engine Options: 5.0L V8
  • Horsepower: Approximately 292 hp
  • Fuel Economy: Estimated 11 mpg city / 14 mpg highway (expect even worse in real-world driving)
  • 0-60 Times: Roughly 7.5 - 8 seconds
  • Towing Capacity: Around 7,000 lbs (check specific vehicle configuration)
  • Trim-Level Features (G500):
    • Standard Features: Leather upholstery, wood trim, heated front and rear seats, sunroof, premium sound system, navigation system, automatic climate control, cruise control, power windows and locks, keyless entry.
    • Off-Road Features: Full-time four-wheel drive, locking front, center, and rear differentials, low-range gearing.
    • Safety Features: Anti-lock brakes (ABS), electronic stability program (ESP), traction control, front and side airbags.
    • Exterior Features: Alloy wheels, running boards, spare tire carrier on the rear door.
The G500 was the main trim level offered in 2004. The 5.0L V8 provided adequate power for both on and off-road situations, though its fuel consumption was a significant drawback. The locking differentials are a key feature that separates the G-Class from many other SUVs and contributes to its exceptional off-road capability. Interior appointments were luxurious for the time, making it a comfortable, albeit thirsty, vehicle.

Analysis

What Problems Does the 2004 Mercedes-Benz G-Class Have?

Frequently reported problems with the 2004 Mercedes-Benz G-Class often revolve around its complex systems. Rust is a significant concern, especially in areas with harsh winters where road salt is used. It commonly affects the body, undercarriage, and door hinges. Electrical issues can arise, including problems with the power windows, door locks, and alarm system. Transfer case issues are another known weakness, potentially leading to expensive repairs.

Long-term reliability concerns include wear and tear on the suspension components due to the vehicle's weight and off-road capabilities. The brake system can also require frequent maintenance. Engine oil leaks are not uncommon as the vehicle ages.

Recalls for the 2004 G-Class were issued for various safety-related issues. It is important to check the vehicle's VIN with the National Highway Traffic Safety Administration (NHTSA) to ensure that all applicable recalls have been addressed. Premature wear of the front brake lines, which could lead to brake failure, was a recall concern on some models. Check the specific history of any potential purchase.

While the G-Class is known for its robust construction, the cost of maintaining its luxury and specialized components contributes to higher long-term ownership costs than other SUVs.

How long will the 2004 Mercedes-Benz G-Class last?

With good maintenance, a 2004 Mercedes-Benz G-Class can last well over 200,000 miles. Many owners report exceeding this mileage with regular servicing. However, consistent neglect can significantly shorten its lifespan. Proper maintenance is crucial, including regular oil changes, transmission services, and addressing rust promptly.

Long-term durability is a mixed bag. The engine and drivetrain are generally robust if well-maintained. However, the electrical system and body are prone to issues over time. Rust remains the biggest long-term threat, especially in colder climates. Careful preventative care is key to maximizing its longevity.

Most solid and reliable vehicle I’ve ever owned. Never let me down or left me stranded or stuck. So much nicer than my Land Rover Defender. My only complaint is that it sacrifices fuel economy for power, and it doesn’t need as much power as it has.

What Technology & Safety Features are Included?

The 2004 Mercedes-Benz G-Class features a navigation system, which was considered advanced for its time. The entertainment system includes a premium sound system with a CD player. Driver-assistance features were limited compared to modern vehicles, primarily consisting of cruise control.

Safety features include anti-lock brakes (ABS), electronic stability program (ESP), traction control, and front and side airbags. These were standard safety features for vehicles in its class during that era.

Optional features may have included upgraded leather upholstery and enhanced sound systems, but the options list was relatively limited compared to newer vehicles.

Crash test ratings for the 2004 G-Class are difficult to obtain from the IIHS or NHTSA. Due to its low production numbers and unique construction, it was not frequently subjected to crash testing. However, its robust body-on-frame construction provides a degree of inherent safety.

Compared to modern vehicles, the 2004 G-Class is lacking in advanced driver-assistance systems (ADAS) such as lane departure warning, blind-spot monitoring, and automatic emergency braking. Its technology is dated but functional for its time.

2004 Mercedes-Benz G-Class Prices and Market Value

The 2004 Mercedes-Benz G-Class (G500) had an MSRP of approximately $75,000 - $80,000 when new. Current used market prices vary greatly depending on condition, mileage, and location, but can range from $20,000 to $40,000 or more for well-maintained examples.

Depreciation has been significant, but the G-Class holds its value better than many luxury SUVs due to its iconic status and limited production. Factors affecting resale value include: overall condition, rust presence, maintenance records, mileage, and the presence of desirable options. The G-Wagen mystique keeps demand high, even for older models.

2004 Mercedes-Benz G-Class Cost of Ownership

The 2004 Mercedes-Benz G-Class is **costly** to own. Insurance premiums are high due to its value and repair costs. Fuel economy is terrible, leading to significant fuel expenses. Maintenance and repair costs are also high due to the specialized parts and labor required. Rust prevention is essential to avoid expensive repairs. Long-term ownership involves budgeting for potential mechanical issues and bodywork. It's far from economical.

2004 Mercedes-Benz G-Class Insurance

Insurance for a 2004 Mercedes-Benz G-Class is moderately priced, reflecting its status as a Vehicle with strong safety ratings and
reasonable repair costs.

How Does the 2004 Mercedes-Benz G-Class Compare to Other Vehicle?

The 2004 Mercedes-Benz G-Class competed with other luxury SUVs like the Land Rover Range Rover, Lexus LX 470, and Cadillac Escalade. In terms of off-road performance, the G-Class surpasses the Escalade. The Range Rover offers similar off-road prowess but with a more refined interior. The Lexus LX 470 is generally more reliable than the G-Class and offers a smoother ride.

Regarding features, the Escalade provided more modern technology for the time. The G-Class focused on its core capabilities, offering a more spartan (but luxurious) interior. The Range Rover provided comparable luxury, with more advanced features at that time.

In terms of reliability, the G-Class falls short of the Lexus LX 470. The Escalade can also be more reliable, though not always. The Range Rover has its own set of reliability concerns.

Regarding price, the G-Class was expensive when new, and used models retain a premium.

Alternatives: A Lexus LX 470 offers similar luxury and better reliability. The Land Rover Range Rover offers comparable off-road capability with more modern features. If off-road prowess isn't essential, the Cadillac Escalade offered more tech for the price.

Ranks #693 SUV

Final Verdict: Is the 2004 Mercedes-Benz G-Class a Good Vehicle?

The 2004 Mercedes-Benz G-Class is ideal for buyers who prioritize off-road capability, iconic styling, and a luxurious interior over fuel efficiency and low maintenance costs. It's a statement vehicle more than a practical choice.

Whether it's worth buying depends on budget and expectations. A well-maintained example with a thorough inspection for rust and mechanical issues *might* be worth it if you understand the ownership costs. Avoid models with extensive rust or questionable maintenance history. Used is the only option, and lower mileage is preferable, but condition trumps mileage. Be prepared for expensive repairs.
