Aylesbury-based Olympian 5100 (G650UPP) rests in Leighton Buzzard High Street. A handful of buses from Aylesbury are still outstationed at Leighton Buzzard to operate town routes. This bus was formerly the Mix 96 bus, wearing first a black livery, later white, between 1994 and 2002. Sister 5101 and Trident 5431 are the current Mix 96 buses.
