Of the cars mentioned, I prefer Caldina. I have been with Allion and its too light and the rear bumper goes off even after a bicycle guys hits you. The new premio is just an allion. You will always want to compare it with the older version and you will just be disappointed. I disposed and got a caldina. Its a wonderful car, it picks very well, handling is excellent, excellent fuel consumption, spacious inside and more importantly coz its a hatchback!
However, you will need to drop your ambition of hire with a caldina. It is too executive for that job! For hire look for NZE and a white one for that matter.
