Unless your current car is really eating your money or you live and work where that has parking issues, if you are going for Vitz, with the same price range, you can have a Yaris that will be a much more reliable choice. You will not save money getting a Vitz since both have similar running costs yet share the same platform unless you really need a hatchback for a single person and really trust a mechanic who knows how to work on Vitz that would be fine.
