Congratulations on ur purchase,osama. i ve been driving a brand new alto for about 5 months, the only thing i didnt like about it was the very soft suspension and very hard steering. the car belonged to my friend, i was forcing him to get EPS in it but luckily, he changed the car and got a new honda city 
apart from steering and suspension issues (both of which can be dealt with) the car was very gud.i used to hit 140km/h with 4 people on board on petrol (not something to boast though) the best thing was fuel economy.
My suggestion to you would be, first, change the tires to 165 size and 2ndly, if u feel the steering is a bit too hard, get an EPS into it. EPS would fit right in without any alterations because they take it off from japanese alto which is same as our local alto. would cost less then 8000rs , depending on where you buy it from. other then that, i wud recommend u to wear seatbelt ALL the time and drive safe
