### **Pros and Cons of Buying Mercedes-Benz W213 E450 (2021) Upper Roof Molding (Left & Right) as a Standalone Part**
#### **Pros:**1. **Aesthetic Enhancement** The upper roof molding (also known as the roof drip rail or side skirting) improves the car s appearance by giving it a more refined, factory-like finish. This can help reduce the "cheap" look of aftermarket modifications or minor damage.
2. **Protection Against Elements** The molding helps deflect water, dirt, and debris away from the roof and side windows, reducing the risk of water seepage or dirt accumulation inside the cabin.
3. **Prevents Rust & Corrosion** By shielding the roof edge and side panels from moisture and road grime, the molding helps prolong the structural integrity of the car, especially in regions with harsh weather conditions.
4. **Completes a Restomod or Restoration** If you re working on a project car (e.g., restoring a W213 to showroom condition), these moldings are often part of the original trim package. Installing them ensures a cohesive, factory-aligned look.
5. **Easy to Install** Unlike full-body panels, these moldings are relatively simple to fit, requiring only basic tools (adhesive, trim tools, and possibly a heat gun for plastic parts). Most DIYers can handle the installation without professional help.
6. **Cost-Effective Compared to Full Panels** Replacing just the upper roof moldings is significantly cheaper than buying and installing entire side panels or roof sections, making it a budget-friendly upgrade.
7. **Available in Matching Colors** Mercedes offers these moldings in various colors (e.g., black, silver, or matching the car s paint), allowing for customization to suit your preference.
8. **Potential Resale Value Boost** A well-maintained W213 with original or high-quality aftermarket moldings may appeal more to buyers looking for a "complete" car, potentially increasing its resale value.

#### **Cons:**1. **Limited Functionality Without Full Restoration** If the rest of the car s exterior (e.g., side panels, rear cladding) is mismatched or damaged, the moldings alone won t fully enhance the appearance. They may look out of place if the car is otherwise modified.
2. **Potential for Poor Quality Aftermarket Parts** If purchasing from a third-party seller (rather than Mercedes or an authorized dealer), there s a risk of receiving low-quality, mismatched, or poorly fitted moldings. This can lead to gaps, misalignment, or premature detachment.
3. **Adhesive & Installation Challenges** Improper adhesive application can cause the moldings to peel, warp, or fall off over time. If not installed correctly, they may trap moisture against the car s body, leading to rust.
4. **Limited Availability of Original Parts** While Mercedes still sells OEM moldings, they may not always be in stock, and ordering directly from the manufacturer can be time-consuming and expensive compared to aftermarket options.
5. **Cost of Aftermarket Alternatives** High-quality aftermarket moldings (e.g., from brands like **AeroVironment, K&K, or EuroCarParts**) can be pricey, sometimes costing as much as OEM parts. Cheaper alternatives may lack durability or fit properly.
6. **Time-Consuming for DIY Installation** If the moldings require trimming, sanding, or precise adhesive application, the process can take several hours, especially for beginners. Rushing may result in a poor finish.
7. **Not a Performance Upgrade** Unlike engine or suspension modifications, these moldings do not improve the car s performance, handling, or fuel efficiency. They are purely cosmetic and functional (in terms of weather protection).
8. **Potential for Voiding Warranty (If Applicable)** If the car is still under warranty, improper installation of aftermarket parts (even if they re technically moldings) could void certain coverage, depending on the manufacturer s policies.

### **Conclusion:**Buying and installing upper roof moldings for a **2021 Mercedes-Benz W213 E450** is a **low-risk, high-reward** decision if done correctly. The benefits improved aesthetics, weather protection, and rust prevention outweigh the drawbacks for most owners, especially those who:
- Are restoring or maintaining the car to showroom condition.
- Want a simple, cost-effective way to enhance appearance.
- Plan to keep the vehicle long-term.
However, if you re not committed to a full exterior refresh or lack the patience for precise installation, the effort may not justify the outcome. Additionally, **sourcing high-quality parts** (either OEM or reputable aftermarket) is critical to avoid disappointment.

### **Recommendation:** 1. **Source Parts Wisely:**- **OEM (Mercedes-Benz Original):** Best for exact fit and finish, but more expensive and slower to obtain.
- **Aftermarket (AeroVironment, K&K, or EuroCarParts):** High-quality alternatives with better availability and pricing. Avoid no-name brands to prevent poor fits or material issues.
- **eBay, RockAuto, or Specialty Mercedes Forums:** Good for finding used or discounted moldings, but inspect for damage or mismatches before purchasing.
2. **Prepare for Installation:**- Clean the roof edge and side panels thoroughly to ensure proper adhesion.
- Use **high-temperature adhesive** (e.g., **3M 5200 or Permatex Extreme**) and a **heat gun** for plastic moldings to prevent warping.
- Follow a **step-by-step guide** (e.g., from **YouTube channels like "Mercedes-Benz Repair Guides"** or **W213 forums**) to avoid common mistakes.
3. **Consider a Full Exterior Refresh:**- If the car s side panels, rear cladding, or lower rocker panels are damaged or mismatched, prioritize those first. Moldings alone won t hide major flaws.
4. **Budget Accordingly:**- **OEM moldings (left right):** $200 $400 (depending on color and dealer markup).
- **High-end aftermarket:** $100 $250 per set.
- **DIY installation costs:** Minimal (adhesive, tools, and time).
5. **Final Verdict:**- **Worth it if:** You want a polished, factory-like finish and are willing to invest time in proper installation.
- **Not worth it if:** You re not committed to maintaining the car s exterior or expect the moldings to drastically change its appearance without complementary work.
For most **W213 owners**, these moldings are a **smart, relatively inexpensive upgrade** that pays off in both aesthetics and long-term protection. Proceed with careful part selection and meticulous installation for the best results.
