In fiscal year 2003, UA one-step buses were introduced for two consecutive years, using bodies manufactured by Nishinippon Shatai Kogyo for the first time in 30 years since the last bus was discarded in March 1974 because, as mentioned above, Fuji Heavy Industries had ceased the manufacture of bus bodies.
2003年度は昨年度に引き続きUAワンステップが導入されたが、上記にもある通り、富士重工がバス車体製造を終了したため、1974年3月廃車分から実に30年ぶりの西日本車体工業製のボディが導入された。
