I bought alto in may 2006 and am really satisfied with almost all the parameter that a buyer looks for in a mid segment car...I was lucky as I bought this all new made up alto at the lowest price ever which I have mentioned below.
some pros#
1)low priced
2)A/C car
3)spacious
4)mileage
5)amazing aerodynamic looks (with coloured bumpers)
cons#
1)pick up when the A/c is on
Although my car has done just around 2500kms but its still giving a mileage of 13-14kmpl(with A/C on) in city driving which is satisfactory.
I also have fitted my alto with 13 inches alloys with tubeless radials , spoiler , rear view mirrors(both) , body coloured bumpers and fog lamps in front (which ive never seen till date on any other alto(trust me guys my car looks chic with just a additional investment of about 25k.
