Citroens are again good looking, but technically not that strange. The smaller cars have a lot of parts in common with other brands and their smallest is also sold as Toyota and Peugeot, if I am correct (I used to work in car business, but I'm not so into it anymore).
The bigger ones also share a lot of features with sister brand Peugeot. So technically Citroens are very normal, except for the hydraulic suspension on the more expensive models.
