Swift feel versus other cars

YangCheolIn

Just got a check-up and the springs are on correctly, bushing on the driver-side rear is on its way out (nissan said), and I'm at 52k miles. The breakdown: at freeway speeds everything is awesome. The car sinks into turns and feels like it is gripping. Awesome. But in the city (ours has some of the worst roads in the country), the bumps are real. They are loud. Potholes sound like loud crunches, and if there is a change of level of concrete, the bumps can be felt. In the city, my friends brz and m3 and my uncle's sl55amg are more comfortable on these potholes and bumps and make less noise. Is this just the cabin? Are the shocks in the other cars just better at absorbing shock from potholes and uneven concrete? Genuinely interested in an answer not from a salesman.
