### **Pros and Cons of Buying a Mercedes-Benz W212 Rocker Panel Skirt Molding (2010 2016 E350/E550, Part #189-996563)**
#### **Pros:**1. **Improved Aerodynamics and Fuel Efficiency** The skirt molding reduces air turbulence under the car, which can slightly improve fuel economy, especially at highway speeds. This is particularly noticeable in larger, heavier vehicles like the E350/E550.
2. **Enhanced Styling and Aesthetics** The skirt molding gives the car a more aggressive, sportier look, aligning with the W212 s sleek design. It also helps maintain a cleaner undercarriage appearance, which can be appealing for show cars or those who prioritize presentation.
3. **Potential Protection for Undercarriage** While not a primary function, the skirt can help deflect minor debris (like small rocks or road grime) from hitting the lower body panels, reducing the risk of minor scratches or corrosion over time.
4. **Compatibility with Aftermarket Mods** If you plan to add other undercarriage modifications (e.g., diffusers, lower spoilers, or exhaust systems), the skirt molding can serve as a base for integration, ensuring a seamless look.
5. **Easy Installation** The W212 s design allows for straightforward installation of the skirt molding, typically requiring only basic tools (no welding or extensive bodywork). Many owners report being able to complete the job in a few hours with minimal effort.
6. **Resale Value Boost (If Well-Maintained)** A car with a properly installed skirt molding may appeal more to enthusiasts or buyers who appreciate a polished, complete appearance, potentially adding a small premium to resale value.
7. **Weather and Road Debris Defense** In areas with heavy rain, snow, or road salt, the skirt can help keep moisture and grime from accumulating under the car, reducing rust risks in susceptible areas.

#### **Cons:**1. **Minimal Performance Impact** While the skirt may improve aerodynamics slightly, the real-world gains in fuel efficiency or handling are negligible for most drivers. The W212 was not designed as a high-performance car, so aerodynamic tweaks have limited effect.
2. **Cost Relative to Benefit** The part itself is not extremely expensive (typically $100 $300 depending on source), but if you re not planning other mods, the marginal benefit may not justify the cost. Labor is minimal, but time spent installing it could be better used on more impactful upgrades.
3. **Potential for Poor Quality or Fit Issues** Aftermarket parts can sometimes have fitment problems, especially if sourced from lower-quality suppliers. The W212 s body structure is precise, and a poorly made skirt may not align perfectly, leading to gaps or misalignment that detract from the appearance.
4. **Maintenance and Wear Concerns** The skirt molding is exposed to road debris, rocks, and minor impacts. Over time, it may crack, peel, or require replacement, adding to long-term costs. Plastic or rubber skirts are more prone to wear than metal ones.
5. **Overkill for Daily Drivers** If you primarily use the car for commuting or casual driving, the aesthetic upgrade may feel unnecessary. The W212 is already a comfortable, reliable vehicle, and the skirt adds little functional value for most owners.
6. **Installation Challenges for DIYers** While generally straightforward, some owners report difficulty aligning the skirt perfectly, especially if the car s undercarriage has accumulated dirt or rust. Cleaning the area thoroughly beforehand is essential, and improper installation can lead to a sloppy finish.
7. **Limited Availability of OEM Parts** Mercedes-Benz no longer produces the W212, so finding genuine OEM skirt moldings can be difficult. Most options come from third-party suppliers, which may vary in quality. Always check reviews before purchasing.

### **Conclusion:**The **Mercedes-Benz W212 rocker panel skirt molding (189-996563)** is a **cosmetic upgrade with minimal functional benefits**, making it more of a **style or enthusiast-oriented modification** than a practical one. It is best suited for owners who:
- Want to enhance the car s appearance for show or personal preference.
- Are already investing in other undercarriage or performance mods.
- Drive in areas with harsh weather or road conditions where undercarriage protection is a concern.
- Have the time to install it properly and maintain it over time.
For **daily drivers or those prioritizing practicality**, the cost and effort may not be justified. However, if you re already working on the car s aesthetics or enjoy DIY projects, the skirt molding is a **low-risk, relatively easy upgrade** that can contribute to a more polished look.

### **Recommendation:**- **Buy it if:** You enjoy customizing your car, plan to add other mods, or want a cleaner undercarriage appearance. Opt for a **high-quality aftermarket part** (e.g., from **Mercedes-Benz Parts Experts, RockAuto, or reputable European suppliers**) to ensure a good fit.
- **Skip it if:** You re on a tight budget, the car is primarily a daily driver, or you prefer to focus on more impactful upgrades (e.g., suspension, exhaust, or interior refinements).
- **Installation Tip:** Clean the rocker panels thoroughly before installation, use high-quality adhesive (if applicable), and take your time aligning the skirt for a professional finish.
- **Budget Consideration:** If you re unsure, consider a **single-side test installation** to see if you like the look before committing to both sides.
Ultimately, the skirt molding is a **subjective upgrade** its value depends on your priorities. For most owners, it s a **nice-to-have rather than a must-have**, but for enthusiasts, it can be a satisfying part of a larger customization project.
