The overall experience with the car has been great. I have driven more than 47000 Kms. over the last 1.5 years. The car is sturdy and feels firm on the road. It inspires confidence. The car is currently returning an impressive mileage of 19 km to a liter.
However, the most irritating part about the car is that within 1.5 yrs it has started rattling. Maruti needs to do something about the built quality and ensure that the body/plastic/glass rattling doesn't happen. Learn from the European cars.
