South of Burleigh Heads is a Bustech single door Mercedes O405NH, 599 (599FIB - honest!).
Nearest the camera, leaving Pacific Fair, is another Mercedes O405NH Bustech, 635 (101GWD). Heading for Burleigh Heads is seemingly identical 826 (826GTL). Both date from 2002, but 826 is on a Volvo B7RLE chassis.
Sister vehicle to 826 is B7RLE 828 (828GTL). Oddly 827 is two years older and is a Mercedes O405NH Bustech.
Yet another variation on the theme, this 2002 vintage Bustech is on a Volvo B12BLE chassis. 839 (839GWF) was displayed at the 2002 Sydney Bus Show, on the Volvo stand, and won the 'Bus of the Show' award. It is seen in the Pacific Fair Mall.
861 (861HUT) sports the new Bustech VST body on a Volvo B12BLE chassis. The deep plastic grey skirt is probably more practical when it comes to repairing occasional damage, but the appearance is probably an acquired taste.
