The 1980 Mercedes Benz 450sl, a classic roadster admired for its style and engineering, is unfortunately known for being susceptible to rust, like many vehicles of its era. Owners and enthusiasts should be aware of common corrosion points to properly maintain and preserve these iconic cars.
One of the primary areas where rust develops on a 1980 450SL is around the wheel wells. Both front and rear wheel wells are prone to rusting, extending towards the rocker panels and potentially affecting the jack points. Careful inspection behind the driver and passenger side front wheel wells, as well as the rear wheel wells, is crucial. The rocker panels themselves are also a common rust location, and this can spread to the jack ports, compromising structural integrity.
Another often overlooked rust-prone area is the top of the front fenders, specifically just above the headlight assemblies. Rust here often originates from the inside out, making it harder to detect early. Regular checks in this area can help catch corrosion before it becomes extensive. Additionally, the trunk area, particularly around the battery, is another spot where rust can accumulate and should be inspected frequently.
Leaks also play a significant role in accelerating rust. Faulty trunk seals, roof seals, as well as door and window seals can allow moisture to penetrate and lead to corrosion. Checking under the thick foam rubber floor mats inside the car for dampness is a good indicator of potential leaks. Similarly, inspecting under the carpeted plywood floor lid behind the rear seats can reveal hidden water accumulation. A moldy smell inside the car is another warning sign suggesting leaks and potential rust issues.
Beyond rust, it’s worth noting a couple of mechanical points for 1980 450SL owners. The subframe has been identified as a potentially weak area in these models, and the timing chain should be checked for elongation or stretch as part of regular maintenance.
Given their vulnerability to weather-related rust, storing a 1980 Mercedes Benz 450SL in a garage or using a leak-proof car cover when not in use is highly recommended. While these cars are known for consuming fuel, their charm and classic appeal make them worthwhile for enthusiasts who are prepared for diligent maintenance and care.
