Q. Is Tata cars made of very low quality steels? I bought a Zest xt petrol model in 2014, now it's body is rusted and damaged.

Yes. In 2011, I brought a Toyota etios liva and my friend brought TATA Indigo. My car has completed 10 years. no rust or oxidisation of metal sheet developed. Whereas the bottom end of metal sheet of my friend's car has completely rusted and small rust holes formed all around. It may be due to the poor quality metal sheets. Companies use such metal sheets for cost cutting. Usually companies never reveal the quality of metals and plastics they use. We should take more informed decision about the long term reliability of the metals and materials before we buy.

There is nothing such as that. I work as a contractor with one of the spare parts supplier of tata motors and I've seen how these parts are designed, manufactured, tested, quality check, rejected in the whole line process. Tata uses a good amount of steel in their cars and trucks. The issue is with the person's negligence of taking care of thier products. I my self owned indica vista 2009 and just sold it to reputed car resellers last month. No rust, no contamination, no radiation nothing. They checked the whole car not only with eyes and assumptions but they used certain devices to check the paint, steel, rubber, plastic, paper everything. Got a descent value for my 14 years old car just because I maintained it nicely. So it's not about the steel, it's about the steal.

No it's the other way round.. actually they use heavy gauge sheet that's why their cars r heavier than maruti that results in their low average compare to maruti
