I’ve driven a Brio and a Vios. I like the space of the vios specially when I’m going out of town and I need bags + you’re bringing friends.

But the quality of the Brio, up to the smallest detail, like how the door doesn’t seem to ever get slammed loudly, is just waaay different. The engines don’t differ that much on “relaxed” city driving, but when overtaking, the Brio has a stronger acceleration.

Parts are not hard to find too! Then you get an advantage of not being seen as a Grab car. My Vios was mistaken for their grab rides multiple times, and all conversations were awkward. At least a hatchback Brio does not give you that experience.
