Does your copen robe shake as hell over slightest pits in road???

I have 2015 copen robe, and I think there is a problem in it's suspension. It shakes a lot even there is only slight up and downs in the road. I showed it to several mechanics and they all told me that it is because car is small, but i always felt it is abnormal to shake that much. In my area there is no any other copen robe so i can't drive another car and see how much they shakes. So please help me by sharing your experience and solutions.
