What is this?
Firstly this thread is about the automatic cuore which has no rival YET.
Secondly, Cuore CNG and Alto VXR CNG are no rivals, because they are in a different class altogether. 850cc vs. 1000cc may seem a small difference in crowded city conditions but a giant leap on highways where you actually use your engine to its potential.
No car is perfect for everybody, comfort depends on your bone structure and usual driving posture. I feel more comfortable in the Cuore but others feel better in an Alto.
For quality I would say it does not take much to spoil a car but it takes a little effort to keep it like new for 3 to 5 years.
However, two very positives of Cuore are the brake boosters and steering. Dude, get a test drive and then re-list the questions you have after that.
