Availability: For older or less common vehicle models, used ignition modules might be more readily available than new ones, which may no longer be in production.
Immediate Compatibility: A used ignition module from the same make and model of vehicle is likely to be immediately compatible, reducing the risk of compatibility issues that can arise with aftermarket parts.
Reduced Downtime: Finding a used ignition module can be quicker than ordering a new one, especially if the new part is on backorder or has a long lead time, reducing vehicle downtime.
