I am driving Maruti Zen Estilo from past 5 years and I have never faced a single major problem with the car. It has a superb comfort level. The interior of the car is extremely good. It is low maintainance car very high quality. Look wise it has a very cute design. It is a small car so it gets easy to park it in a small area and one also do not have to worry about the traffic in most of the time.
With ground clearance of 165mm ( 6.5 in") , it can go through rough route easily.
Zen estilo has a superb balancing and even after driving it for so long it still give mileage of minimum 18km per litre. It is very spacious car and if you are looking forward to buy a car within the range of 5 lac then Maruti Zen Estilo is the best choice.
