Tata Group chief Ratan Tata today said that Tata Motors' Nano has 'wasted an early opportunity' due to teething problems, but the company will do everything to undo the tag of 'poor man's car'.

Tata, who is also the Chairman of Tata Motors, said: "Many efforts were made to discredit the product. We never pushed it (Nano) as a poor man's car, but as an affordable family car. Whatever stigma is there in the market, we will undo it."

Asserting that the very concept of Nano is a robust one, he said: "The launches of similar small cars by others vindicate our belief that this segment was missing in the product line."

He further added that Tata Motors was "not much in competition with others as far as pricing of it is concerned".
