 In fact, if CO2 is the main greenhouse gas, the amount require to make Mars habitable also makes it uninhabitable. Nor can any such atmosphere hold enough H2O to matter.  Vast amounts of some neutral, stable, GHG are required. ArNe2 would be perfect, if only it existed. CFCs possibly, though they do eventually break down.

WikiPedia tells me that ArNe2 does exist; at 4K. I'd worry about what making it stable at room temperature would do to the rest of chemistry, but if one assumes that the rest of chemistry is unchanged then the next question that comes to mind is whether ArNe2 is an anaesthetic like several of the inert gases are.
