It's a Smart car. So not very large.
It's the ForTwo, the proper titchy Smart with only the two seats.
And it's the Cabrio, so the roof's not there.
But it's even more minimalist than that, as it hasn't got doors either - instead it has a rear-hinged lifting bar on each side instead. The overall effect is of something that's barely there at all, and it just looks like the most fun since the Mini Moke.
I've tried finding it on the Smart website(s), but couldn't, so I'm afraid I can't point those interested at pictures of it.
