Not many people have the ability to donate a complete ambulance.

MAGEN DAVID ADOM is Israel’s emergency medical services organization. Its 30,000 team members mobilize a fleet of 1,700 ambulances, Medicycles, helicopters, and other emergency vehicles to save every life possible. It is responsible for Israel’s national blood supply and responds to all terrorist and mass casualty situations.
About 90% of Israel’s EMTs and paramedics are volunteers. They take no pay for their courageous service. But they cannot save lives without vehicles and medical supplies.
