A West-African migrant, who entered the Spanish territory of Ceuta from Morocco was caught curled up next to a car engine, while another was hidden behind the back seat of the Mercedes-300 car.
Spanish police found the men late on Sunday during a customs check at El Tarajal, near the Moroccan border.
The migrating pair from Guinea got first aid, having suffered from a lack of oxygen, Spain's Guardia Civil police said.
The two illegal migrants did not have any papers, and were identified in the statement only as "TD and AB from Guinea Conakry". They are also under official investigation now.
