I thought Iriz has good handling. Why do you dislike it? CVT? Poor NVH?
1) I love the firm suspension, but it is too stiff - bouncing and body motion everywhere. I wonder if proton has performed pre-loading adjustment on the stock suspension. Body roll is present even with aftermarket anti roll bar installed. If one takes corners like a champion over rumble strips and expansion gaps of the highway, be prepared to have it skip a few beat and sometimes having its rear coming out slightly.
2) I hate the side mirrors because they have huge blind spots.
3) Rubber band effect of the CVT. It poses a threat when you want to overtake or exit a junction.
4) Total cost of ownership including service maintenance and parts replacement doesn't reflect the status of a local car for the masses.
However, only my passengers love it because of its rear seats that have good thigh support and headrests.
