I've had my CR-Z for over a month now and I still get excited every day to drive it. The handling is excellent and I feel safe, though the sport mode can certainly pick up the pace. The gas mileage is good but the great build, comfortable seats, and awesome technology make that just a bonus. Of course the only downfall is not having a backseat anymore, but there is plenty of trunk space.
The three driving modes, comfortable seats, and amazing look both inside and out.
Putting in seats and seat belts would make the car more accessible to more people.
