Most German cars have stiff suspension. Certainly the 20" low profile tires will further contribute to that stiffness. The attraction is that usually handling is better. I doubt that many traditional Buick drivers will care about the improved handling. It is not likely any test ride would be driven aggressively enough that it would make a difference.Having just test driven it, I did it for fun and to compare it to the new Lacrosse. There really was no comparision in fit and finish between the two ( looked like it wasn't even made by the same company), and the Buick also had many more features....at a $37,000 (Cascada) to $40,000(Lacrosse) cost difference. I honestly also did it to experience what a sports suspension with 20 inch wheels felt like. I have a friend who drove to the Outer Banks from Northern Delaware in her husband's few year old Corvette last summer, and all she talked about was how difficult it was on her because of the sports suspension ride. I can not express enough to be sure to test drive this new convertable on some roads in need of repair before signing on the dotted line. Yea, it was pretty hard on the bumps.....but some people seem to like that, I guess. Very nice to see Buick making a convertable again, though.
