I can't comment on the accent or mirage but if you need trunkspace, the jazz has loads of it when you fold down the rear seat. However, the vios for me is a good all around car with excellent fuel economy and ease of maintenance. The only thing I don't like about it is that it is low. I've gone over some high humps where the vios has skidded. The jazz hasn't done this for me. I find it lower than any of our other cars. Both cars are comfortable enough for me and are easy to park due to their small size.
