I gave my 2009 Tata Nano LX 2 years ago for 75k which had only clocked 5000 KMs. Its very difficult to sell this car and getting even 75k was hard for me that time. Most were asking less then 60k! Worst thing is to listen negative feedbacks of this car.
One of buyer was negotiating with me to a scooter price because he wanted to buy a new scooter the other day and a car would be better for the same price. My final price was 75k with a lost amount of 1.35 Lakhs. He bought a scooter instead.
Nano is a good car if driven within city but I suggest you to find newer models of Nano. Above 2012 is better because it will be very much improved from factory.
2009, 2010 and 2011 had some issues which was resolved within the dealer service center (recall) but Tata service centers are not trust'able because I had bad experiences multiple times which ended up selling.
Issues my car had: Highly vibrating engine, Loud engine noise, Engine heating to high degrees which causes rear bumper to melt, Rusting in many places, Gear shift not smooth, Clutch not smooth, Fail to crank engine (as if no battery connected but no issues with battery) and etc. These issues were expressed to service centers many times but they either fail to fix or create new issues after fixing other.
