2007: “We purchased a fleet of 8 25-passenger buses from nabi, who purchased Optima bus. They received the bid because they could guarantee delivery by the first part of july. On aug 30, the first buses started to arrive and continued coming in over the next couple of months. 2 of the buses needed to replace the engines that blew up on the way from the factory to delivery. Multiple and ongoing problems sidelined the buses to the point where we could neither accept them nor operate them. After technicians worked on the buses, we accepted them by the end of dec. To enable nabi to get paid. …”
