Bought Alto LXI in late march 06 and it has run about 2500 kms. Till 1000 kms, the vehicle was pretty tight since the controls were very new, a pleasant transformation happened after 1000 kms - first service and its like magic.
Smooth to say the least and very comfortable at the wheel, power steering does really help. I would have definetely regretted if I had cosen the LX, just for the wheel comfort - no compromise on that.
I have driven it through the best highways in the country to the worst ones, villages roads , even roads where only mud and stones are visible and in hilly regions with ghat sections. Good companion on all roads, Power Steering ROCKS when it comes to hills and curves.
AC is the best in the country in its category - cools very fast and stays cool for a long time.
Talking about fuel efficiency, it has promptly comforted me with 18KMPL in City and 23+ on the highways. No other car in india can give this satisfaction and smile.
But, its not been totally complaint free, the vehicle as such is superb and has not troubled me on the things what was shown on paper. Problems are on other factors like - with AC on, the vehicle is definitely under powered. I would have loved to have the 1.1ltr VXI model if it existed, poor WagonR would have gone bankrupt if Alto VXI was around.
With full grown 4 people inside or 4+1 kid sitting, the vehicle still dosent deliver what is expected - again blame goes to the paltry 800cc engine. These are the only imaginable flaws in the Alto LXI.
Overall - Star in its own right, Alto LXI delights in city and in driving comfort at the wheel.
