I've driven one, albeit only for an hour as I had a blowout and got the car changed. In that time I can't honestly think of anything positive to say about the way it drove, but then it was never ever going to be a car I liked.
Is it for ferrying kids around? I can sort of see the appeal of the walk in height for either young kids or someone who struggles to get into more traditional cars, other than that I can't think of anything that I thought was good. The steering was terrible, it was very, very slow, quite noisy, looked pretty poor inside with that horrible stereo front citroen like to put on, rolled round every corner and was just generally not a car I'd ever chose to be in.
How new is the car you're looking at? You'll get no end of comments about it being french and will therefore fall apart but my own personal experience of french motors is that whilst they aren't on a par with anything japanese for lack of stuff breaking they break just as often or little as pretty much everything else. They tend to be put together in a rather stupid way though so it can be more difficult (and so expensive) to sort some consumables. About the only other thing i'd say is don't burden yourself with a modern diesel (which you may not be looking at anyway) unless you do the miles to warrant it.
