Understanding the R107 Chassis Code
Before diving into identification specifics, it’s crucial to understand the significance of the R107 chassis code. This designation denotes the model's generation, differentiating it from other Mercedes-Benz models and providing a crucial starting point for identification. The "380" specifies the engine displacement, indicating a 3.8-liter V8 engine—a key characteristic of this particular variant.
Where to Find the VIN Number
The Vehicle Identification Number (VIN) is the single most important piece of information for verifying a vehicle's authenticity and history. This 17-character alphanumeric code contains a wealth of data about the car's manufacturing details, including the year, production location, and specific options.
Where is the VIN located on an R107?
The VIN on an R107 Mercedes-Benz is typically located in several places:
- Dashboard: Look on the driver's side of the dashboard, usually visible through the windshield.
- Driver's Side Doorjamb: Check the sticker on the driver's side doorjamb. This sticker often includes the VIN along with other vehicle specifications.
- Engine Compartment: The VIN may also be stamped on a metal plate in the engine compartment.
Once you locate the VIN, you can use online databases (some are subscription-based) or contact Mercedes-Benz directly to access comprehensive vehicle history reports.
Engine Bay Inspection: Key Identifying Features
The engine bay offers several visual clues that can help authenticate a 380SL and identify any modifications or potential inconsistencies:
- Engine Type: Confirm the presence of the M117 3.8-liter V8 engine. Look for the engine code stamped on the engine block itself. Differences in the engine code might indicate modifications or replacements.
- Casting Numbers: Pay close attention to casting numbers on various engine components. These numbers can provide further information about the engine's origin and manufacturing date.
- Hoses and Components: Check the condition and type of hoses, belts, and other components. Significant deviations from the original specifications might indicate previous repairs or modifications.
Identifying Original Features and Options
Many original features can be used to authenticate your R107 380SL. Here are some key areas to inspect:
