Well... If I have to choose from, my priorities would be following:
- Vitz or Passo / Boon (personal liking / disliking asides, both seem equally and reasonably Good to me)
- Brand New Cultus AGS
(Regarding their Pros and Cons, they have been discussed here multiple times on this forum. You can use the search button above, to find the details)
If you are inclined towards used JDM Vitz or Passo / Boon, I would recommend to self-import one, instead of buying from market. Will be a bit costly, but will not cost you any trouble in coming 3-5 years, other than regular, routine maintenance.
