Nissan micra is a nice car . I bought it around 4 years ago and still using it for regular purpose. Nissan is the first bramd who got push button feature in budget cars but almost all cars around its range have got it. The major reason people buy nissan is because of its features like push button start and other security functions. Even after 4 years it is working good. Talking about its maintance cost , it cost around 7 to 8k for one service. The major drawback of this car is that it has less after sale value due to its design. I personally bought it because of its features and not because of its design .I compromised design for better features .
At last my opinion is that now one has a lot of better alternatives .Ill not say it is a bad car but one can have a look on other .
