The **BMW 51377137597 rear left/right quarter panel molding** for the **E64 M6 (645Ci/650i)** from the **2004 2010 model years** is a precision-engineered aftermarket replacement part designed to restore the iconic, aggressive stance and factory-level aesthetics of this legendary luxury grand tourer. Crafted from high-quality, durable materials typically a blend of **polyurethane or ABS plastic** this molding is meticulously shaped to match the original BMW design, ensuring a seamless fit along the rear quarter panel, extending from the lower edge of the door to the base of the rear wheel arch. The molding features a **smooth, contoured profile** with subtle, factory-inspired creases and a glossy or matte finish (depending on the variant), allowing it to blend flawlessly with the vehicle s bodywork while maintaining the M6 s distinctive, muscular silhouette. Engineered to withstand the rigors of daily driving, including exposure to UV rays, minor impacts, and environmental elements, this molding is often reinforced with **ribbed or textured surfaces** to prevent warping or cracking over time.

Whether installed as part of a full paint restoration or a targeted cosmetic upgrade, the **51377137597 quarter panel molding** ensures that the E64 M6 retains its timeless, high-performance presence turning heads with its sharp, aerodynamic lines and unmistakable BMW heritage.

### **Pros and Cons of Buying a BMW E64 M6 6.5L (645Ci/650i) Rear Quarter Panel Molding (Part Number: 51377137597, 04-10)**

1. **Authentic Fit and Finish** BMW s original quarter panel moldings are designed to match the vehicle s body perfectly, ensuring a seamless and factory-like appearance. Aftermarket parts may not align as precisely, leading to gaps or misalignment.

2. **Durability and Material Quality** BMW uses high-quality materials (likely painted plastic or composite) that are resistant to UV damage, cracking, and warping over time. This ensures longevity compared to cheaper aftermarket alternatives.

3. **Resale Value Preservation** Keeping original parts (even if damaged) can help maintain the vehicle s resale value, especially if you plan to sell or trade it in later. Buyers often prefer cars with fewer aftermarket modifications.

4. **Consistency with Other Panels** If you ve already replaced other moldings (e.g., side skirts, front fenders) with aftermarket parts, using an OEM quarter panel ensures visual harmony across the car s bodywork.

5. **Potential for Future Repairs** If the molding is damaged, having the correct OEM part ensures compatibility with BMW s repair procedures, reducing the risk of improper fits or alignment issues.

6. **Aesthetic Continuity** The E64 M6 is a highly sought-after model, and maintaining its original styling details (including moldings) enhances its collector appeal.

1. **High Cost** OEM BMW parts are significantly more expensive than aftermarket alternatives. A single quarter panel molding for an E64 can cost **$300 $600 **, depending on availability and seller. For a full set (left right), prices can exceed **$1,000**.

2. **Limited Availability** Finding a genuine BMW part number (51377137597) may be difficult, especially for older models. Some sellers may offer "reconditioned" or "used" parts, which could have hidden damage (e.g., cracks, paint chips, or misalignment).

- Removing the wheel arch liner.

- Disconnecting the rear quarter window regulator (if applicable).

- Ensuring proper alignment to avoid gaps.

- Reapplying body filler and repainting for a seamless finish.

If you lack mechanical experience, professional installation will add **$200 $500 ** to the cost.

4. **Potential for Counterfeit Parts** Some sellers may offer "OEM-style" or "BMW-compatible" moldings that are not genuine. These may lack proper fitment, material quality, or paint adhesion, leading to premature failure.

5. **Time-Consuming Process** The job is labor-intensive, requiring patience for sanding, priming, and painting to match the existing bodywork. Rust or corrosion on the original panel may also need addressing before installation.

6. **Alternative Solutions Exist** For cosmetic purposes, aftermarket moldings (e.g., from **Eibach, ATS, or local body shops**) can be significantly cheaper (**$50 $150 per panel**) and often come with installation kits. However, they may not match perfectly and could require additional modifications.

---

- You prioritize **authenticity and long-term durability** over cost savings.

- You re restoring or maintaining a **high-value collector car** where original parts are essential.

- You have the **time, skills, or budget** for professional installation and paint matching.

- You ve already invested in other OEM components and want consistency.

- You re on a **tight budget** and the moldings are purely cosmetic.

- You lack experience with **bodywork or paintwork**.

- You can find a **high-quality aftermarket alternative** at a fraction of the cost.

- The moldings are **minorly damaged** (e.g., small chips) and can be repaired with filler/paint instead of full replacement.

Then, an **aftermarket or DIY repair solution** may be more practical.

---

1. **Verify the Part s Authenticity** Confirm the part number (51377137597) matches your vehicle s year (04 10) and engine variant (645Ci/650i). Check with a **BMW parts specialist** or **eBay Motors "Sold Listings"** to gauge fair pricing.

2. **Compare Prices** Look for **used OEM parts** (often cheaper than new) on platforms like **eBay, Facebook Marketplace, or BMW specialty forums**. Avoid sellers offering parts without proper documentation or photos.

3. **Assess the Damage** If the molding has **minor cracks or chips**, consider **body filler and touch-up paint** instead of full replacement. For **severe rust or warping**, replacement may be necessary.

4. **Consider Aftermarket Options** If budget is a concern, brands like **Eibach, ATS, or local body shops** offer moldings that closely resemble OEM parts. Ensure they re **painted to match** your car s color.

5. **Budget for Installation** If DIY isn t an option, factor in **labor costs** (typically **$150 $300 per panel** at a BMW specialist).

6. **Prioritize Other Repairs First** If the **underlying bodywork has rust or damage**, address those issues before replacing moldings to prevent future problems.

- **Buy the OEM part** if you re committed to a **full restoration** and can afford the cost/time.

- **Skip it** if the moldings are minorly damaged or if you re working with a limited budget opt for aftermarket or repair solutions instead.

For most enthusiasts, the **cost-benefit ratio leans toward aftermarket** unless the car is a **showpiece or future investment**. Always weigh the **practicality vs. perfection** in your project.
