Q. Dzire VDi is best or Brezza VDi?

Both are good vehicles. If you are passionate about driving - I would suggest Brezza. And if you are looking at practical requirement - Lower cost of running as well as lower initial price - Dzire would be better. Also remember dzire is available in Petrol while Brezza is not.

Both are capable vehicles from Maruti brand . Brezza will provide good ground clearance,and upright driving position, and has sporty interior colouring tones. Desire will provide better boot space, classic interior. Brezza will be a good choice here.

With ATM transmission, when I want to overtake,I shift to the M mode, for more power.Also use M mode if I am driving uphill ,or on muddy roads.
