Thomas Saf-T-Liner C2
 The Thomas Saf-T-Liner C2 (often shortened to C2) is a Type C (conventional-style) school bus produced by Thomas Built Buses. In production since 2004 the C2 is based on a Freightliner C2 chassis itself derived from the Freightliner M2 Business Class medium-duty conventional. It was introduced as the replacement for the Thomas Conventional and Thomas Saf-T-Liner FS-65; the latter was produced alongside the C2 until December 2006.
