Having "test driven" my friend's 1.0EZ Viva, I must say that the car is quite nice..
The steering is nicely weighted, not overly light like in the Kenari, and it's kinda spacious for a car that small. Legroom and headroom is ample, and does not get crampy. Seats are also decent for a car at that price.
That being said, however, the one I was driving was kinda reluctant to shift down when I floor it, but engine vibrations were kept at a minimum, although engine noise can clearly be heard.
Cruising along at 120km/h at the NSE is just fine, although a little faster can get unnerving.. Ride is also kinda bouncy..
Overall, I think the manual one would be a more fun car, but as a bare basic car, I'm quite pleased with it. The other thing is that the build quality is kinda

.. but that's not the point. the point is that this is a basic point A to point B car, in which this one delivers just well.
