The Tata Nano faced significant challenges including opposition from farmers over the Singur plant location, quality concerns from being positioned as India's cheapest car, and difficulties reaching its target market in small towns and villages. While it received over 2 lakh bookings initially, most customers already owned a car. Sales have been far lower than competitors like the Maruti Alto. However, Tata made improvements by restructuring distribution, offering financing options, enhancing safety features, and rebranding the Nano to focus on its performance and features rather than price.
