Tata Motors is seeing very difficult times in terms of the sales of its passenger cars.  The Nano is still sliding downwards rapidly and in August managed to sell only 3,200 units of the car.  The Indigo range including all models is stuck in the 4,000 range and the Indica range in the 5000 plus range.  This is especially sad considering the fact that Tata has diesel engines in all its cars with the exception of the Nano.  The engineering aspect of all cars has improved considerably but it is perhaps poor marketing that is letting down the company.
