 Certain high value parts such as electronic modules, alternators, starter motors, infotainment systems - even complete engines or transmissions - may be removed if they are still serviceable and can be profitably sold on; either in "as-is" used condition or to a remanufacturer for restoration.This process of removing higher value parts from the lower value vehicle body shell has traditionally been done by hand.A labour intensive process, that has meant it is uneconomical to remove many of the parts.
