one thing though....I really like the interior design but I would also be concerned with how it'll age.
I don't have a solid opinion on the design aging topic, but I think we agree that it's a subjective matter. Usually, French cars often have that unusual (maybe a bit flamboyant?) look, whether inside or outside, as opposed to the German way.
I can think of German design as a suit, which is there isn't much you can add to make it exciting, but it is elegant and will remain so even after some time. French cars can be the casual clothing line that has a better flexibility to add new touches here and there that may go out of fashion after some time, but you then you see different opinions on whether that design was good or not. Some people will still like it, while some will not.
Funny enough, although the Peugeot's new interior theme is as modern as it gets, I see some retro touches in it such as the two layer on the passenger's side of the dashboard which I remember seeing in old cars from the 70's and the 80's. I can't say exactly from where I drew my impression, and I'm not on my PC right now so I can't provide images to prove my point so excuse this one
You are quite correct about the Clio continuing the MPV like design path, but I think that the real game changer is its interior. The 4th generation had an awful interior and it was its main negative point. I hope the new one will be a much more complete product.
I'm a fan of the original Renault Clio and its predecessor, the legendary Renault 5 which my uncle used to have in addition to Renault 12 (my Grandfather) when I was a kid so I still like Renault!
Back to the Clio. I'm glad I wasn't the only one who noticed the MPV profile. I didn't like how the French companies implemented it in their cars (that applies for the Peugeot 207 as well). The Megane is good looking but the Clio isn't so much (personal opinion)
However, the new interior is really nice with the Volvo inspired touchscreen.
