A Krystal bus is by no means your ordinary bus. Krystal Enterprises, a California-based producer of luxury limousines, and one of the leaders in their industry, has applied their stylish and sophisticated talents to producing a series of buses like no other.On the outside, a Krystal bus is customized stretch section built on a standard chassis. The chassis ranges from a Ford F-series front to a slick, dangerous-looking International 3200 (picture a luxury bus with the face of a semi truck, and you\'ve got it). Inside the custom section, though, is Krystal\'s sense of perfection and luxury.
