Here in Costa Rica they refer to all side by sides be it 2 seats or 4 as "mula" not very fancy but very appropriate considering that these things will go just about anywhere a mule could, Yamaha calls theirs Mule, but Tico's and maybe all Spanish countries have assigned the female gender to it and have chosen to call it a "mula" I better end it here and go and see what I sometimes affectionately call my wife "mula" is making for dinner.
