Detailed Explanations
Engine Reliability: The M112 V6 engine in the C240 is generally robust. However, the earlier years (2001-2003) sometimes experienced issues with oil leaks and sensor failures. The later years (2004-2005) benefited from refinements and improved manufacturing processes, leading to better overall reliability. Regular oil changes with the correct type of oil are critical for maintaining engine health across all years.
Transmission Issues: The automatic transmission in the C240 could be problematic, particularly in the earlier models. Slipping gears, rough shifting, and complete transmission failure were reported. The 2004-2005 models saw improvements in transmission design and control software, resulting in a smoother and more reliable experience. Regular transmission fluid changes, using the recommended fluid, are essential.
Electrical Problems: The W203 generation, in general, was known for its electrical gremlins. Issues ranged from malfunctioning sensors and faulty window regulators to problems with the instrument cluster and central locking system. The earlier years (2001-2003) seemed to suffer more frequently from these problems. Later models (2004-2005) had some of these issues addressed, but electrical problems can still occur due to the car's age.
Rust Issues: Rust is a significant concern for many older Mercedes-Benz vehicles, including the C240. The earlier models (2001-2003) were particularly susceptible to rust, especially in areas like the wheel arches, door bottoms, and around the trunk lid. While the later models (2004-2005) benefited from improved rustproofing, they are still not immune to rust, especially in regions with harsh winters and road salt. Thoroughly inspect any potential C240 purchase for rust.
Interior Quality: While the overall design of the C240's interior was generally well-received, the quality of the materials used in the earlier models (2001-2003) was sometimes criticized. The later models (2004-2005) saw improvements in the quality of the plastics and trim, resulting in a more premium feel. Leather seats, if equipped, require regular conditioning to prevent cracking.
Fuel Efficiency: The C240's fuel efficiency is relatively consistent across all model years, given its engine size and weight. Expect to get around 18-22 mpg in the city and 25-30 mpg on the highway. Driving style and maintenance condition significantly impact fuel economy.
Resale Value: As with any used car, the C240's resale value depends on factors such as mileage, condition, and location. However, the later models (2004-2005) generally command slightly higher prices due to their improved reliability and features.
Common Issues (General): Besides the specific issues mentioned above, the C240 can experience common problems like minor sensor failures (e.g., mass airflow sensor, oxygen sensors), occasional fuel pump problems, and issues with the climate control system. Regular maintenance and prompt repairs can help prevent these issues from escalating.
Maintenance Costs: Maintenance costs for the C240 can be higher than those for some other cars in its class. This is due to the cost of parts and the specialized knowledge required to work on Mercedes-Benz vehicles. Preventative maintenance is key to keeping costs down. Neglecting maintenance will inevitably lead to more expensive repairs down the road.
Available Features: The features available on the C240 are relatively consistent across all model years. Standard features typically include power windows, power locks, air conditioning, cruise control, and a sound system. Optional features may include leather seats, a sunroof, a navigation system, and upgraded sound systems. Later years might have slightly updated versions of these features.
Safety Features: The C240 offers standard safety features for its time, including anti-lock brakes (ABS), electronic stability control (ESP), and multiple airbags. Later years might have minor improvements in these systems, but the fundamental safety features remain largely the same.
