* Through the rear seats: Some W126 models allow for partial or complete rear seat removal or folding. This *might* provide access to the trunk latch mechanism or cabling. This requires checking your specific model's seat removal instructions (often found in the owner's manual or online).
* Through the interior trunk release: Even if the vacuum system is dead, there's likely a manual cable or rod connected to the interior trunk release. You might be able to access and manipulate this cable or rod from inside the car, either by removing interior trim panels or by carefully exploring existing openings. This requires some careful probing and potentially specialized tools.
* From the underside of the car: If you're comfortable working underneath the car, you might be able to access the trunk latch mechanism from below. This will require identifying the latch mechanism and potentially removing parts of the underbody panel. This is the most challenging option.
* Professional Assistance: Your best bet might be a locksmith specializing in classic Mercedes-Benz vehicles, or a reputable mechanic. They have the tools and experience to open the trunk without causing damage.
Important Considerations:
* Avoid forceful entry: Trying to pry open the trunk can easily damage the bodywork, paint, and the locking mechanism itself.
* Safety First: Always disconnect the battery's negative terminal before working with any electrical components, especially if you're working under the car.
* Consult a Repair Manual: A repair manual specific to your 1982 W126 model will provide diagrams and instructions that greatly assist in understanding the trunk mechanism and access points.
Attempting these methods without proper knowledge could result in damage to your car. Consider professional help if you're unsure.
