I bought this car in 1998 as I wanted to upgrade my existing car. I drive an average of 65 km everyday and it has been giving a good average - in the region of 16 km./l without AC and 12-13 with AC on.
The car has neat interiors and its jellybean design looks cute. However, on outstation drives on one or two occasions, the AC conked off (This was in the month of June with temp hovering in the mid-forties.)
It is roomy for people with average height. However, as all of us are exceptionally tall, we need to push the front seats back to be able to sit comfortably. We have already clocked 71K plus mileage and are looking for a new car. I shall not go for a Zen this time, as I am looking for a car with more legroom.
