The Thomas Vista is a model line of buses that was manufactured by Thomas Built Buses from 1989 to 1998. Produced nearly exclusively as a school bus, the model line was also sold in commercial-use configurations. To improve forward sightlines for drivers, the chassis design of the Vista combines elements of conventional buses and transit-style school buses (as well as those from smaller buses).
Following the 1998 acquisition of Thomas Built Buses by Freightliner, Thomas ended the production of the Vista in favor of the standard Saf-T-Liner Conventional. While the 2004 Thomas Saf-T-Liner C2 was not intended as a direct replacement, elements of its body design incorporated features previously used in the Thomas Vista.

During the early 1980s, school-bus manufacturing in the United States underwent a period of relative turmoil, as the exit of the baby boom generation from the public education system created a sharp decline in student populations. In the late 1970s, the US federal government had significantly upgraded crash protection standards for school buses.
While safety had long played a key role in the marketing and development of school buses, designers were forced to take a proactive stance to increase innovation to production. By improving the sightlines of the driver, the chances of preventing accidents improved, as well.
Following the acquisition of Thomas by Freightliner in 1998, the Thomas Vista was withdrawn in favor of the Thomas Saf-T-Liner Conventional and Thomas-Saf-T-Liner FS-65. As the Navistar 3600 chassis was designed specifically for the Thomas Vista body, its production ended as well.
