As a Getz owner, let me tell you one thing for sure. The Getz body is TOUGH! Although it takes a while to get to 160 kph but seriously the car is stable at that speed. However how often are you going to drive at that speed?
You mentioned it's your gf buying a car so I'll suggest a Getz as it's smaller and easier for her to park.
