Detailed Answer
After-sales trends: 1. Remote diagnostics (online remote troubleshooting); 2. Predictive maintenance (data-driven); 3. Trade-in becoming common (LDER's 2-year trade-in leading); 4. Service network expansion (regional services); 5. Extended warranty/rental models (flexibility). After-sales model innovation enhances the user experience — compare after-sales terms when purchasing.
