 Although the original fleet did not include any minibuses, a large number of Mercedes-Benz vehicles were introduced from September 1986 on a high-frequency route in central and northern Glasgow; it did not prove profitable and was converted to full-size operation a year later, with many of the minibuses transferred to other SBG subsidiaries. Another unusual vehicle in the Kelvin fleet was the only Leyland Lynx bought by Scottish Bus Group, which was delivered new in 1989. Six rare Leyland Lion double-deckers were ordered in 1988, but owing to a large cut in Kelvin's peak vehicle requirement they did not enter service with the company and were instead sent to Clydeside Scottish.
