Shuttle buses can range from mid size to small "mini buses". They are not typically considered a large bus. Typically when looking for sale buses the person is looking for a passenger number under 25. If you're shopping for a used bus and need to carry a higher passenger count you might consider looking at coaches in stead of used shuttle buses. Many churches choose the shuttle bus when looking for a bus for sale because of the manageable size, fuel usage and ease of repair.
