Good design poor customer service. Review on Tata Nano

I purchased NANO LX  3 months back. I was using alto since last 4 years.  I am really impressed with design. lot of space compare to alto. Drive quality is really good (for city on highway I am never going to try). Actually it is better city car then other small cars. I think one should not drive it on highway. After first service it is giving  17+ kmpl   (previously it was around 15) -u can't expect more in our city.

I recommend this car if you want to use with in city. It should command premium in con-justed city roads.

pros:

space

drive quality

easy to drive in traffic

smaller turning radius

mileage (17+ in city)

cons:

poor customer service

battery below driving seat

engine is a bit noisy  worried how much noise it will make after 2years.

not designed for highway

update:

I tried nano on highway 200kms , no heating milage 24.5 km/liter. Only some problem on rough rodes.

after second service

asked service center to install safety kit....they say "we do not know when it will come"...after giving poor feedback on follow up...kit was available with in two days and installed.

after service...ac is not working on "1" speed...2, 3 it is ok. Doors are not shutting properly.

and horn has stopped working after 1 week.

and with a.c. engine looks under powered.

Now I am feeling that buying nano was a wrong decision....good design but no quality.

edit: service experience is really poor. Do n't expect anything on warranty name. Better to spend on any other brand. just say tata to tata.
