I think what makes the Aria special to me atleast is to see the TATA badge on a product that looks like it has finally come of age. The company is expanding its portfolio with new and relevant products perfectly suited to the Indian auto market and many auto markets abroad. TATA's great strides in product quality, fit and finish, from the time of their rust-bucket range a.k.a the Sierra, Estate and early versions of the Sumo and Indica, to new generation models (though not great looking) like the Vista, Manza and Aria, is commendable.
Besides, I'm sick of Innovas and Taveras anyway. Another new model on the streets is always a good thing.
