I have a swift vxi bought 2 years back! Excellent comfort, good mileage(12 in city and 18 in highway). But it gives only 11-12 in highway if you drive between 140kms/hr to 170kms/hr.
If you live in a hilly place like ooty, kodaikanal or yercaud, this is not the right car. The pickup is dead slow on inclined areas(hills). But it really rocks in the plain area highways that no other mid size car could come near to swift.
This is the car were I have seen the brakes the best! Drive at 120kms/hr and apply breaks. It will come to stop in few seconds. The surprising thing is - the passengers wont be pulled forward during brakes. You will just be sitting as if you applied break driving any car in just 40kms/hr. This is the best thing I like. TO show off to my friends, I drive fast and apply gradual brakes which stops the car very smoothly. You wont feel the brakes. Notice the speedometer needle. It comes very fast from 140kms/hr to 0kms/hr without any discomfort to passengers.
Otherthing I like is "sharp cuts". Just cut the steering in high speed and still the car is still well under control. I think it is becuse of that the width of car is more when compared to other cars.
