10. Sanchez
Ah, the Sanchez. The bike you could use to drive up a 90 degree angle mountain face in San Andreas with passers by thinking nothing of it. As you've all seen from the promotional materials from the guys at Rockstar, there was a push in promoting off road transportation. One that was highlighted a considerable amount was the Sanchez. We saw one of our protagonist raging this beast around the new open world map, so suffice to say, it looks like it could be a common mode of transport. Also, judging from the trailers, it seems a lot of the map will be dedicated to the agricultural landscape. If proven so, this could be your saviour. As much fun San Andreas was, being stuck in a field in an Emperor was not. So as far as ground transportation goes, a Sanchez may just be your best friend.
