---

### **Cons of Buying a GM Gr. 9.772 Electric Clock**

1. **Age and Wear**

- The clock may be **decades old**, meaning it could be worn out, rusted, or damaged internally. If not properly maintained, it may require significant restoration work before it functions correctly.

4. **Cost of Restoration**

- Purchasing replacement parts (e.g., a new motor or gears).
