HOW MUCH DOES A USED CITIZEN L20VII 5M7 2000 COST?
The price of a used CITIZEN L20VII 5M7 2000 depends heavily on machine condition, control condition, spindle hours, bar feeder, tooling, live tooling, coolant system, chip management, and maintenance history.
Current used-market listings for 2000 L20VII machines are generally request-for-quote, while comparable L20VII machines from nearby years have recently been listed around $7,500–$14,900, depending on year and configuration. A current used L20 VII listing outside the exact 5M7 configuration is also advertised at approximately $35,000, showing how equipment package and machine condition can significantly affect asking prices.
For a CITIZEN L20VII 5M7 2000, a reasonable used-market estimate is approximately $12,000–$30,000 USD, with heavily equipped, rebuilt, or exceptionally maintained machines potentially selling above this range.
| Machine Condition / Configuration | Estimated Used Price |
|---|---|
| Higher Hours / Basic Configuration | $12,000–$17,000 |
| Good Condition / Standard Configuration | $17,000–$22,000 |
| Well Equipped / Bar Feeder + Live Tooling | $22,000–$30,000 |
| Rebuilt / Extensive Tooling / Automation | $30,000+ Possible |
The final value should be based on spindle condition, machine accuracy, CNC control, bar feeder, live tooling, tooling package, maintenance history, and whether the machine is available under power for inspection.
