I must say that this is not a comparison, that is between HONDA CITY and NISSAN SUNNY.....Sunny is more like a Corolla, Civic or Lancer.
Nissan Sunny is literally most comfortable than any other in its class in Pakistan.....Corolla, Civic, and Lancer are good but with a little bit bumpy ride, Honda City 2001 is good again but not as comfortable as Nissan Sunny 2001.
Fuel consumptionmay be similar with negligble difference.
Spare parts depend on locality, like in Rawalpindi one may find Nissan parts cheaper and easily than one in Faisalabad....however Honda City's parts are available in more cities.
Finally I must say Nissan Sunny gives you a relatively smoother, and comfortable ride with a sound proof cabin....and Honda city is good in terms of parts availability , NOT the price.
