I have purchased tata vista aura model petrol version in feb 09, & still after usage of 2700kms the avaerage is 9.25km/ltr feel cheated by the company on claims of 15.9km/ltr.
Taken the car to authorized workshop but no satisfactory explanation was available on milage also door switch on driver doors was faulty which they were unable to replace due to non availability as spare as confirmed new model. Even the dealer was not helpful astonishing to see vista qudrajet on insurance papers instead of vista aura & till date they have not done anything for correction despite several reminders
The availability of required accessories is also very poor. Whenever you have to use gear lock driver seat always have to displaced back & for unlock also. It is appealing due design & space but really performance is not encouraging considering the milage factor i shall not recommend this petrol version to my near & dears.
