Mine (04 1.6) has a space saver spare wheel. Even the Citroen salesman tried to tell me that it had run flat tyres, but a quick poke around in the boot revealed the truth. The tailgate hinge and boot false-floor seem quite high, so I think we've given up boot space in order to retain the spare wheel, rather than the other way around. Of course, we can always put the roof up and leave the plastic boot cover thingy at home if we need to use that space for luggage. I'm not sure that any production Pluriels have ever had run flat tyres. Could it have been a feature of the prototype that never made it into production, but which didn't get removed from the press pack? A Pluriel without a spare wheel well could perhaps have been given a deeper boot, but only if the folding mechanism could have been redesigned to stow the rear screen at the greater depth, so I can't see this being a last minute change to the design. Given that there's space for a spare wheel in the current car, why would Citroen choose not to supply one? Run flat tyres must be more expensive, aren't they? What other use could they make of that space? A bigger fuel tank perhaps, or a specially designed 15" custom picnic hamper? :-)
