Wattbike Atom V2 - will it fit in the back of an Audi A3?

I'm due to pick up a Wattbike Atom V2 tomorrow. I think with the seatpost fully down, seat and handlebars removed, it should fit fine it I ease it in on a sideways angle. Measurements do look a little tight though.

Has anyone done this? Long shot but don't want to make a wasted journey.
