They actually look like a football helmet, but it actually looked like a coconut. That's where the names come from. Translated from Spanish, Coco stands for coconut.
Like almost all vintage cars on the island, the Cuban state (Grancar) owns them all and the drivers have to pay a daily rate to use them and an extra amount per kilometer.
The taxi can carry a maximum of three people, who are then very tight, plus the driver who sits in front.
You see the Coco taxis everywhere in Havana.
The taxi is not that comfortable for longer trips, but they offer a good experience that is worth trying. They charge about 1 CUC per mile and are only meant for tourists because you don't see the locals taking a Coco Taxi.
