The 100 series fleet of “fishbowls” was received in 1961 as part of the new fleet acquired by AC Transit to replace the aging buses inherited from the predecessor Key System Transit Lines. A radical new design compared to the original “old looks,” the “new looks” were manufactured by General Motors Truck & Coach. The 100s were a ‘suburban model’, having no rear exit door, and were fitted with high backed seats to be used for AC’s Transbay service. They operated from 1961 until the early 80s. After retirment, many were sold to bus lease companies and other operators. Some are still in service with these companies today. Coach #100 was purchased by National Coach Sales in 1983, a bus leasing company, and had been stored at Eastshore Lines, a San Francisco charter operator. It was given to AC Transit sometime in 1996-97 and was then fully restored by the District’s Central Maintenance Facility in East Oakland. This specific fleet was air conditioned on delivery, but over the years, units were removed.
