Chill guys,let someone claim as much as they want.The fact STILL REMAINS that TATA is numero uno Commercial vehicle manufacturer because their vehicles are robust,and engines durable.As I have already said the 2.0lt tcic in old 207 and the 3.0 lt di in 407 have already proved their metal,that's exactly why these vehicle still sell so well.As about kilometers,well recently I sat in a taxi Vista TDI which had done 1.98 lakh kms without engine being opened,and it runs daily as part of its job.No company can survive in todays cut throat market if their engines are unreliable,as the choices are immense,IMHO!
