My Swift will be completing 4 years in July 2009. So though of sharing some info about the past 4 years
I really can say that it was the best decision I took at that time without even waiting for the car to hit road and then get some initial user reviews. I just went for the brand "Maruti" and it worked wonders.
My car has been a great experience for me.
I never had to do any maintenance apart from normal servicing. (i guess that the biggest value of the brand "Maruti")
Recently I went for a trip to Tuljaput-Pandharpur and clocked around 700kms on my car. It gave me a fuely efficiency of 17.1 kmpl with AC.
In City (Pune) it gives me around 13 kmpl.
At last I will say that this is really a great car giving me comfort of driving as well and fair on my wallet :)))
PS: Love your Car, and it will return you the favour :)))
