I like the look of the OmniCity/OmniLink Scanias, much better looking than the Wright Eclipses and Geminis which look rather tired now. The Volvo chassis with the Wright body(pun very much intended!) is much, much better though, especially the Geminis.

All OmniCity's be it single deck, double deck or artic have vertically mounted engine like the AW and VWL120-144 which is part of the reason why they look stange at the back(notice also the n/s rear has lots of air intakes), the OmniLink has the standard engine layout.
