I was the first person to buy the new zen estillo vxi with K10 engine in sept 2009. Tillnow Ive driven 32000kms, out of which around 5000 kms in the himalays. In hilly areas the road stability is superb just like my 2001 opel corsa.At a speed 80-90kmph it delivers the best millage on highways. On country side roads the suspension proves to be on weaker side. Rear seats requires a lot of improvement for elderly people they keep on changing sides. AC is one of the best which evenly circulates the air in the entire car.
Yes on negative factor which the maruti has still not paid any heed despite various comps is the iron bar in the window near the side rear mirrors. which causes a wide black spot which itself is sufficient to become a cause for a fattal accident even I my self escaped especially at 90* intersections or T points. After 30000km Iam sure Most of you are going to face clutch problem. One thing not a family car but best car in the market at present for lone commuters.
