CCs For Sale: 2013 Smarts – Two For the Price of One?

I’ spotted these two little twins in front of a rural house on the way to our regular hiking spot, and had to stop and find out; are they both for sale? Two for the price of one?

 

The sign on the windshield doesn’t answer that clearly. “For Two”; does that mean $6000 for two? Or is it referring to the name “Fortwo”? Or is it pointing out the obvious, that this is a car for two? Or?
