On my test drive I went to a really bad road with huge holes I even touched a bottom of a car once while driving through it (I intentionally tried to catch some holes). Overall I really liked the handling, though it was a short distance and tried to keep it relatively slow.
I've driven once on a dirt road with lots of bumps and puddles. It handles quite nicely, except for the low ground clearance in front. The bumper was constantly scraping the dirt, but nothing broke or cracked.
