Took a while to find my picture...
2012 Honda Ruckus in a 2010 Honda Fit (and all its 57 cu.ft. glory)... had to take off the mirrors and lay it a bit on its side. This was during my drive to dinner with a friend after buying it (06/04/12). It impressed the sales guy, who helped me shove it in.
It got dark when I finally got home, pic of it emerging from the rear.
Later I fit it in a Dodge Caravan (after I fell and couldn't get the Ruck to run), from sliding door to sliding door, only had to fold down one of the middle row seats and angle it a little towards the back. Sorry, no pic of that.
