I am a swift dzire owner and I purchased the car on the year 2010. And iam not facing any problem till yet. I had used my vehicle for a reading of 50000km. Only the draw back is that you cannot overload the boot as it cannot bare it.
Swift dzire is powered by a 1300cc ddis engine. The full form of ddis is direct diesel injector system. It is made for 5 person maximum. The car gives a good mileage of 25 kmpl on highway and 18 to 20 kmpl in city with a/c. The air conditioner of car works well in all weathers. If you want to purchase a sedan car swift dzire is value for money.
