From the You tube, and thanks, it appears it may be a bit of style over substance. But with the future changes, maybe the EV will be better. I was juggling this and the 5008, but not researched that yet.
I’ve sat in the 408 a couple of times recently and in my opinion your expression “style over substance” fits it perfectly. It is a striking looking car but has a quite cramped interior, so may not be particularly practical.
