Notes
This item comes with two vendors: 
Drix Blackwrench <The Fixer> and Mojodishu <Traveling Trader>. You can dismiss one or both of them to free up a spot for a friend in your party or raid. To bring them back, you must leave the vehicle and cast your mount again.
This is a very special mount/vehicle. When 
[Aspect of the Pack] is enabled, because the mount is a party member, it receives the speed increase, a 30% increase, even faster than when paladins use 
[Crusader Aura], a 20% increase. In a battleground, a flag carrier can ride this mount and will not drop the flag. When the rider or passengers fall a significant distance, the fall damage is taken by the mount and not the passengers (for very high falls, the damage is only partially transferred, and the mount dies on impact). Not to mention this mount is like dropping a Repair Bot if the dungeon is outdoors or otherwise allows mounts to be summoned. Even for instances that do not allow mounting, repairing is often needed after repeated corpse runs, where players may be near an entrance anyways, and could simply gather around the mammoth just outside the instance portal before returning inside.
