Turnaround times are estimates, not guaranteed completion dates. All timeframes are subject to vehicle inspection, confirmation of the repair scope, parts availability, supplier lead times, customs clearance where applicable, and any additional faults discovered during the repair. Overseas parts can significantly extend the total turnaround time. The estimated workshop turnaround begins once the necessary parts are available and the vehicle is ready for the scheduled repair. We will confirm an individual estimate before work proceeds and communicate any material changes.
All listed times are working days, not calendar days. Parts lead time is separate from workshop repair time.
