Q. Which is better to buy between Automatic Verna petrol with sunroof and Honda City?

Go for Verna as it comes with a proper torque converter unlike City's CVT transmission. Pluses of Torque converter are awesome refinement levels, flexible gearing , smoothness while CVT's pluses are infinite gear ratio, on par efficiency with manual counterpart yes certainly better than torque converters efficiency. But CVT's have notorious rubber band effect and crude refinement levels which seriously robs one of driving pleasure the moment you tend to go heavy on right pedal.

I think verna with sunroof is better than honda city's sunroof...

If petrol then Honda cars
