The 2004 Mercedes-Benz CL-Class represents the pinnacle of luxury coupes from Mercedes-Benz. As a grand tourer, it offers a blend of performance and opulence. The CL-Class, in this generation, spans model years 2000-2006. Key trims include the CL500, CL600, and the high-performance CL55 AMG. Original pricing ranged significantly based on trim and options, typically from $90,000 to over $130,000. Its distinctive pillarless design and advanced technology for its time contributed to its popularity.
The Good

The 2004 CL-Class offers strong performance with its V8 and V12 engine options, providing exhilarating acceleration. It boasts exceptional comfort thanks to its luxurious interior and advanced suspension. Its elegant design appeals emotionally, while its solid build quality and Mercedes-Benz heritage offer a sense of long-term value and prestige to the practical buyer, though reliability can be a concern.

The Bad

Maintenance can be costly, and certain parts are difficult to find. Rust can also be an issue, especially in areas with harsh winters. Potential buyers should have a pre-purchase inspection performed by a qualified mechanic.

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

The 2004 Mercedes-Benz CL-Class is plagued by several frequently reported problems, primarily centered around its complex systems. The Active Body Control (ABC) suspension is a major source of headaches, with issues like leaks, pump failures, and strut malfunctions leading to very expensive repairs. The hydraulic system is intricate and requires specialized knowledge to service properly.
Another common area of concern is the electronic system. The car is loaded with sensors and modules, and failures are common. These can range from minor inconveniences like malfunctioning windows or seats to more serious issues that affect the car's drivability. The COMAND system, which controls the navigation, audio, and climate control, is also known to be problematic.
Long-term reliability is a significant concern. The age of the vehicle means that many components are nearing the end of their lifespan, leading to increased maintenance costs. Rust can also be an issue, especially in areas where salt is used on the roads. While recalls for the 2004 model year specifically might be limited at this point, it's crucial to check for any outstanding recalls related to safety or emissions. Overall, potential buyers should be prepared for potentially high repair bills and a need for meticulous maintenance.

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

Given the age of the 2004 Mercedes-Benz CL-Class, most examples will have well over 100,000 miles. With good maintenance, including regular fluid changes (especially for the ABC system) and addressing issues promptly, these cars can potentially reach 200,000 miles or more. However, the long-term durability is heavily influenced by maintenance habits. Neglecting the complex systems will significantly shorten the car's lifespan and lead to catastrophic failures. The ABC suspension and electrical components are the primary weaknesses that will surface over time, resulting in costly repairs. Rust can also become a significant issue, especially in regions with harsh winters.

What Technology & Safety Features are Included?

The 2004 Mercedes-Benz CL-Class was technologically advanced for its time. Standard features included a COMAND system with navigation, a premium sound system (often Bose), dual-zone climate control, and power-adjustable heated seats. Driver-assistance features were limited compared to modern cars but included cruise control and rain-sensing wipers.
Safety features included anti-lock brakes (ABS), electronic stability control (ESP), traction control, and multiple airbags (front, side, and curtain). Optional features included Keyless Go (keyless entry and ignition), massaging seats, and upgraded leather upholstery. The Active Body Control (ABC) suspension, while prone to issues, also contributed to handling and stability.
Crash-test ratings from organizations like the NHTSA (National Highway Traffic Safety Administration) and IIHS (Insurance Institute for Highway Safety) for this specific model year may be limited or unavailable due to the age of the vehicle and the fact that it wasn't always subjected to the same rigorous testing as modern cars. However, Mercedes-Benz vehicles of this era generally performed well in crash tests, emphasizing structural integrity and occupant protection. It's worth noting the CL-Class included features like seatbelt pretensioners and load limiters, contributing to occupant safety during a collision.

2004 Mercedes-Benz CL-Class Prices and Market Value

When new, the 2004 Mercedes-Benz CL-Class ranged from approximately $90,000 for the CL500 to over $130,000 for the CL600 and CL55 AMG, depending on options. As of today, used market prices vary widely based on condition, mileage, and location. Expect to find examples ranging from $5,000 to $20,000. The CL-Class has experienced significant depreciation due to its age, high maintenance costs, and complex systems. Factors affecting resale value include the car's mechanical condition, service history, cosmetic appearance, and the presence of desirable options. Cars with documented maintenance and in excellent condition will command a premium.

2004 Mercedes-Benz CL-Class Cost of Ownership

Owning a 2004 Mercedes-Benz CL-Class is generally considered costly. Insurance premiums can be higher than average due to the car's original price and performance capabilities. Fuel economy is poor, especially with the V12 engine. Maintenance and repairs are expensive, particularly for the ABC suspension and electrical systems. Parts can be difficult to find and specialized labor is often required. Long-term ownership costs can easily exceed the initial purchase price, making it far from an economical choice.

2004 Mercedes-Benz CL-Class Insurance

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

How Does the 2004 Mercedes-Benz CL-Class Compare to Other Coupe?

The 2004 Mercedes-Benz CL-Class competed with luxury coupes like the BMW 6 Series (though a direct competitor arrived later with the E63 generation), Jaguar XK, and Lexus SC430. In terms of performance, the CL55 AMG rivaled or exceeded many of its competitors. Features were generally comparable, with the CL-Class offering a high level of luxury and technology for the time.
However, the CL-Class falls short in reliability compared to the Lexus SC430, which is known for its dependability. The BMW 6 Series (later models) offered a sportier driving experience but could also suffer from reliability issues. The Jaguar XK provided similar levels of luxury but with a more distinctive British flair.
Considering overall ownership costs and reliability, the Lexus SC430 is a potentially better alternative if dependability is a primary concern. If performance is paramount, a well-maintained CL55 AMG is hard to beat, but buyers should be prepared for potentially high repair bills. A newer BMW 6 Series (E63 generation and newer) might also be considered, but research reliability ratings beforehand.

Final Verdict: Is the 2004 Mercedes-Benz CL-Class a Good Coupe?

The 2004 Mercedes-Benz CL-Class is ideal for enthusiasts who appreciate luxury and performance and are willing to accept the risks of high maintenance costs. It's worth buying *only* if you find a well-maintained example with a comprehensive service history and are prepared to address potential issues proactively. A pre-purchase inspection by a qualified Mercedes-Benz mechanic is essential. Given the potential for expensive repairs, it's generally recommended to avoid the CL600 due to its complex V12 engine and focus on the CL500 or, if budget allows and a thorough inspection checks out, a CL55 AMG. It is not recommended for budget-conscious buyers or those seeking hassle-free transportation.

Best luxury performance vehicle for its year

I love the performance of this car. 500 HP cannot go unnoticed. Definitely comfortable too. The adaptive suspension is way ahead of its day. Good styling as well. I love it so far.

Very Disappointed

The air suspension went out at 57k. That was over $2,000. Couldn't put the shifter into drive, told by MB mechanic normal for them to go out. $900. Sensor after sensor goes out. The plastic that shuts the glove box broke at 25k along with the cup holder.. The car has 59k on it and I'm a stickler on taking care of my cars. How they got $100k for this car new is beyond me.
