Think twice when you r buyying NEW MANZA

Dear friends, I bought TATA Manza as a super sedan on August 2010,on November end of 2011 my car got break down and called the service center and they toed the vehicle to CONCERD MOTORS IN MYSORE road,till 15 days they were trying to get the reason that what happen to the car and why its not getting start,initially they said its a rat entry,than diesel pump problem,than some coding problem,at the 25th day they said wiring problem,than they promised me that they will call some engineers from the plant to resolve the problem,and every day they were updating me as wiring kit is coming from the plant,at the end of 50th day they said everything is ready you can take the car,and i took the car out of garage on 24th jan 2012 and on 25th the same problem is occurred friends i am thinking like weather they are inefficient to resolve the problem or TATA Motors are used for this.Its my humble request that whenever you are buying the TATA cars please think at-list 10-15 times,I bought this car with lot of patriotism,love and its a indian car but?
