A good star from Cologne
We acquired this shining star on all roads, a Mercedes-Benz 350 SE W116, directly from Cologne. The car was a 1977 model, complete, roadworthy, and equipped with an automatic transmission. The original interior fittings were retained. This project, therefore, wasn't about a complete reimagining or a full restoration down to the last screw, but rather about repairing age-related body damage.
After nearly 40 years, the Mercedes suffered from rust in many typical W116 areas. The photographic documentation shows these areas in detail. Such pictures are important because they later make it clear what work was actually done and why certain repairs were necessary.
Mercedes 350 SE with M116-V8
The W116 was the first model series to be officially designated as the S-Class. The 350 SE was one of the V8 models positioned below the larger 450 SE. Its 3.5-liter M116 engine perfectly suited the car's character: quiet, powerful, and composed, without making the car feel unnecessarily sluggish.
In this vehicle, the mechanical components remained largely original. The focus was on the bodywork. This is often the right decision with the W116, provided the engine, transmission, interior, and accessories are still in good condition. A well-maintained interior, original details, and intact mechanical components are invaluable in a classic S-Class. Rust, on the other hand, continues to spread if ignored.
Typical W116 rust spots
The Mercedes hadn't suffered any spectacular accident damage or poor pre-conditioning, but rather age-related rust. That sounds less serious than it is. On the W116, particular attention should be paid to the jack points, sills, underbody, wheel arches, door bottoms, fenders, trunk floor, rear quarter panels, window frames, plenum chamber, axle mounts, and areas under trim strips.
It's often under trim strips and rubber seals that you can see how honest an old Mercedes really is. The paintwork may still look decent on the outside, but underneath, rust lurks in folds, edges, and cavities. If only cosmetic work is done, the problem will reappear. Therefore, the affected areas must be opened, cleaned, repaired, and properly protected.
Bodywork instead of routine parts replacement
A W116 is large, solidly built, and of high quality, but not indestructible. The excellent Mercedes quality doesn't protect against decades of moisture, salt, prolonged periods of inactivity, and minor paint damage. The jack points and sills, in particular, often reveal whether a vehicle merely looks well-maintained or is truly sound.
On this 350 SE, the critical bodywork areas were repaired and restored to their original condition. The original paint was retained. This suited the character of the vehicle, as the car was not to be reinvented. It was to be clean, sound, and usable for the long term.
Documentation and return transport to Cologne
Photographic documentation was an important component of this project. It showed the critical areas before and during the work. This is particularly useful for rust repairs on the W116, because the later viewer can no longer see the extent of the work under the paint and underbody protection.
After the work was completed, the Mercedes was returned to its owner. Using our pick-up and delivery service, we brought the 350 SE back to Cologne. This is often the most convenient solution for large, roadworthy classic cars: the vehicle arrives safely at the workshop and is returned to its owner after the work is completed.
S-Class preserved with substance
This Mercedes 350 SE wasn't a disassembled pile of parts or a hopeless lemon. It was a complete, roadworthy W116 with original equipment and age-related rust in the usual places. That's precisely why targeted restoration was worthwhile.
A Mercedes W116 restoration doesn't always have to involve replacing everything. Sometimes the best approach is to preserve the existing structure, thoroughly eliminate rust, and maintain the car's character. This 350 SE remained what it was: a classic S-Class with a V8, automatic transmission, and the three-pointed star on every road.
