@prabhjot & @adisrini1103 , sheet metal thickness by itself is not, as you would agree, an indicator of strength. The question is, whether my "tin-can" is better than your tin can" ie, what aspects of the structure re-inforcements are there in a Punto/Linea which are totally absent in other cars. For that kind of analysis one needs to take a much deeper technical look, which may be a bit beyond the scope of discussion of this forum. Because there too, there is no absolute right vs wrong. No "checklist" to say that a particular item found/missing contributes to superior build quality. Various car manufacturers may have their own variation/interpretation. Amongst the Maruti cars, the SX4, has more than adequate build quality. Yet that did not prevent the demise of a Union Minister, who apparently was not belted in and perhaps suffered severe "stress and shock" levels while not having direct injuries to his body. NOW- if the car had side impact airbags, and he had worn a seat belt,then it could have perhaps reduced the trauma levels and he may have survived.
