I really dont agree with the people who think Manza is a worst car. Being a owner myself, I can say it is one of the best fuel efficient and reliable car. Till now have completed 35000 Km, and its running totally perfect, Just maintain your car properly, it will surely become one of your best car.
Sometimes people complain about the dealer, but the dealer in my area is very helpful up to the mark. No problem with the dealer as such. Always take your car to the authorized dealer, still you face any problem, suggest you to change your dealer.
But for me Tata Manza is one of best sedans.
