Ummmm... Sorry sir but I drove a passo one day. Some sort of special edition, don't remember the name, it was new shape fresh import. ODO read less than 20k km. It felt funny at corners, flying in the wind at speeds above 100kph and poor at acceleration, well at least not faster than swift. Braking was okay(ish) as well.
What I personally feel is that City Idsi possesses out class luxury and comfort in comparison. Several times better interior, seats, drive quality and traction (except braking). And the swift is a far better option as its new, better interior, much lesser road noise inside the cabin, out class braking and traction.
Though personally, I would always go for a city over a swift.
