Considering to buy Tata Nano Twist. Ex-showroom price in my city is Rs 2.40 lacs. For On-road, the price goes upto Rs 2.76 lacs. But during year end offers, they are offering discount of Rs 40k, which brings down final on-road amount to Rs 2.36 lacs. Dealer is giving mudflap guard as complimentary accessory with this car. Is it really a worth buy???
