1.) "Hi Tech Trike" from ADP: http://www.sharecg.com/v/31786/Poser/Hitec-Trike
A very unique, and well made vehicle!
2.) Various scene objs by DJEric: http://djeric.deviantart.com/
Including a Bank facade, an alley way, a staircase, an industrial interior, ...; you'll have to browse his gallery to get to the downloads.
3.) "Old Snowmobile" from 3DGreg: http://sharecg.com/v/31999/3D-Models/Old-Snowmobile
I haven't used this one yet; but it will certainly come in handy.
Here is a quickie scene featuring the "Hi Tech Trike", and the "Bank Facade". The image also contains a work in progress texture for the (non freebie) "Nemesis" bodyglove.
