automatic guy, while it is highly likely that the car will behave normally after overhauling of engine, it seems that you have bought a lemon..if its engine is so bad in just 5 years and the body is in such good condition (meaning its prolly been repaired extensively) besides God knows what is the situation of its suspension, minimize your losses and get rid of it. There's always a lesson to be learned from every endeavour, always thoroughly get a second hand car checked by a reliable denter and mechanic..
Any ways as i said earlier, sell the car and be much much careful while getting another one...God knows how much more trouble this car will bring...
Chici wala's scene is different, he prolly got the car brand new and besides the cars engine went kaput due to water usage in radiator besides having clocked 190K...Any ways best of luck in what ever you decide to do.
