I own a sunshine yellow Nano and has finished 2300km since dec 2009. I really suggest this car only for a city drive as it is fantastic in handling in peak traffics and the plus point of this car is the advanced tech engine and mpfi injection which does not let you know the surges when the AC gets on and off and even when you are climbing a flyover.The leg room and the head room is the best I have seen so far in any other car, me being 6ft after sitting comfortably in the driving seat another 6ft can be accommodated in the rear seat. Even you can place a big suitcase between these two seats and helps for those who need a boot space to carry such heavy luggage.
AC is the best in this car.And some more pros are an average of 14 (peak traffics), 17-18(normal traffic) and 23(highway) with AC on all the times.Also have an ample space to keep your things on the dash and door storage is also good.Lighting is very good and the last of it is getting in and getting out and parking made very simple.
Cons of this car is being a 2 cylinder engine the sound in low revs is not good to ears.Suspension could have been improved.Battery is placed under the drivers seat which I hate the most.There is no provision provided anywhere to fit a small set of speakers.The seats can be improved much better.
Front glass being so wide the ones who are sitting in the front seats can feel the sun very much.And lifting the hood for filling petrol is one more drawback.Rear engine is little dangerous for sudden braking in traffic as you might get hit by your rear car which is common in cities these days.And the last one is vibration.Vibration is high when picking up from 3rd to 4th gear and even the rear view mirror vibrates making rear objects difficult to see.
As good and bad levels each other , nano can be one of the citys best cars with a superb pricing compared to others.
