When I looked at this car before I wondered how you got in as there was no sign of a door. Now some new pictures from a car show have appeared that show how it works. The whole front of the car lifts up. Like some sports cars I've been in it may require some gymnastics to get in. You can also see that the +2 seats are accessed from the rear and face backwards. It's a novel way to fit them in.

I'm so intruiged that I have subscribed to their mailing list to see how things develop.
