---

### **Cons of Buying a W222 S65 AMG**

1. **High Maintenance Costs**

- Mercedes AMG vehicles are expensive to maintain, with **specialized labor, OEM parts, and frequent service intervals** (e.g., valve clearance adjustments every 60,000 100,000 km).

- The **left cylinder head cover** is part of the engine s cooling system; neglecting maintenance (e.g., oil changes, turbo inspections) can lead to **expensive repairs** (e.g., turbo failure, oil leaks).

2. **Common Engine Issues**

- **Oil Consumption:** The M277/M279 engines are known for **excessive oil consumption** (up to 1L per 1,000 km in some cases), requiring frequent top-ups.

- **Turbocharger Failures:** The twin-turbo setup is prone to **wastegate failures, oil leaks, and intercooler issues**, especially if the vehicle is driven aggressively.

- **Carbon Buildup:** The direct-injection system can suffer from **carbon deposits**, leading to rough idling or misfires if not addressed.

- **Left Cylinder Head Cover Problems:** If the original cover is cracked, warped, or leaking, it can cause **cooling issues, oil contamination, or even engine damage** if not replaced promptly.

3. **Complexity and Specialized Repairs**

- The **M277/M279 engine** is more complex than naturally aspirated V8s, requiring **skilled mechanics** for repairs (e.g., turbo overhaul, fuel system cleaning).

- **AMG-specific diagnostics** (e.g., MB Star or DAS tools) are needed for proper troubleshooting, increasing repair costs.

4. **Fuel Economy and Running Costs**

- The S65 AMG consumes ** 12 14L/100 km** in mixed driving, making it expensive to operate compared to smaller luxury cars.

- **High insurance premiums** due to performance and value.

5. **Depreciation and Market Saturation**

- While the W222 holds value, it is **not as rare as older AMG models**, meaning the used market is competitive.

- The **2020 facelift (W223)** introduced updates, making older W222s slightly less desirable to some buyers.

6. **Potential for Electrical Gremlins**

- Like many modern Mercedes, the W222 can suffer from **infotainment glitches, sensor failures, or electrical component malfunctions**, requiring dealer visits.

7. **Noise and Vibration Issues**

- Some owners report **excessive wind noise, road noise, or engine vibrations** at higher speeds, particularly in less expensive trims.

- The **left cylinder head cover** can contribute to noise if it s loose or improperly sealed.

8. **Limited Practicality for Daily Use**

- The **S65 AMG is a performance-oriented car**, not ideal for long commutes or heavy towing (max towing capacity is 1,800 kg).

- The **large size and high weight** (2,300 kg) make it less nimble in city driving.

### **Key Considerations for the Left Cylinder Head Cover (Part #2790160000)**

- **Function:** The cylinder head cover seals the engine, preventing oil leaks and ensuring proper cooling. A faulty cover can lead to **oil contamination, reduced performance, or even engine damage**.

- Oil leaks around the cover.

- Visible cracks or warping.

- Increased engine noise or overheating.

- **Recommendation:** If the current cover is damaged, **replace it immediately** to avoid long-term issues. A high-quality aftermarket cover (e.g., **Aeromotive, K&N**) can be a cost-effective alternative if properly installed.

You **need a practical, low-cost-to-own daily driver** consider a **less powerful E-Class or a used BMW M3**.
