{T}: Add {C}.
{T}: Add one mana of any color. Spend this mana only to cast a Pilot or Vehicle spell.
{3}, {T}: Target Vehicle becomes an artifact creature until end of turn.
If an effect that causes a Vehicle to become a creature doesn't specify its power and toughness, it has the same power and toughness that it would normally have if it were crewed.
Mech Hangar's last ability doesn't count as “crewing” a Vehicle for any ability that would trigger off of a Vehicle becoming crewed.
