I have bought Maruti suzuki 800 in 2014 and I have got very good experience.
This car is on the top on the list at this price point.The biggest reliablility of this car is fuel economy.If you live in a big city like Mumbai you have to spend fuel of worth thousands and with Maruthi Suzuki 800 the fuel costs become very low.
Secondly the maintenance of Maruti Suzuki is very cheap.You will be able to find mechanics very easily.The spare parts of Maruti suzuki is also very cheap and easily accessible from everywhere.Highly recommended!
