Vectorworks is the architectural 2D-3D BIM CAD app for Mac. Much faster and easier to use than AC with a lower learning curve and just as capable. Virtually seamless import/export to AC 2008 and earlier.
Original disks in original box. NOT copies. NOT bootleg. With the original license. With manuals.
Does not include Renderworks (an extra cost). I used it for architectural blueprint drawings where rendering is superfluous. Runs great on a C2D mini. A Universal app, so it will even run on a PPC machine. Roof builder, stair builder, auto dimensioning.
Original cost over 1500, the 2013 version sells in the neighborhood of 2100.
I'll take 150 for it.
