---

### **Cons**

- If you want **unique features**, you may need to modify the installation, which can void warranties or complicate repairs.

4. **Age-Related Wear in Original Parts**

- If the vehicle is **old (e.g., pre-2000s)**, the **original headliner may have deteriorated** due to UV exposure, heat, or poor maintenance.

- Replacing it with a new part may not fully restore functionality if the **underlying roof structure is compromised** (e.g., rust, sagging).

- This is more common in **older vehicles with poor ventilation** in the roof cavity.

6. **Cost of Professional Installation**

- While DIY installation is possible, **professional labor** (if needed) can add significant cost, especially for vehicles with complex roof designs.

- Some dealerships charge **premium prices** for OEM parts and installation.

7. **Limited Long-Term Warranty Coverage**

- If the headliner fails due to manufacturing defects, aftermarket suppliers may not offer full refunds or replacements.
