An interesting implementation of the low floor design exists in Australia, where Custom Coaches makes a "Hybrid" variant of its CB60 bodywork. These buses combine a smaller low floor area with a small underfloor bin for some luggage. Whilst these buses do not provide a full amount of luggage space, they can be used to house more luggage than what can be held inside the bus itself. Another drawback is the arrangement means the section of the bus that is at curb height is very short-consisting of enough space to house the wheelchair area and then rising up, to accommodate the luggage bin. These buses also lack the ability to have a center door.
