What I often like is when production cars have a concept-car like look with features you usually do not have with other cars. (Citroen C4 Cactus just comes into my mind)
The US has different legal requirements for cars to the ECE standards used by most of the rest of the world (US protectionism? Surely not). Unless Citroen / PSA renter the US market and make a special US variant, they won’t be legal until the car is 25 years old and qualifies for an exception.
