Are the fuel efficiency claims for the Nissan Micra accurate?

I've been considering buying a Nissan Micra for its advertised fuel efficiency, but I've heard mixed reviews. Can anyone with personal experience tell me if the stated fuel efficiency is accurate?

Hello John, I've been a proud owner of a Nissan Micra for over 3 years now and I can confirm that the fuel efficiency claims are accurate. I consistently get 40+ mpg on both highway and city driving. I highly recommend the Micra for its affordability and fuel efficiency.

Hi John, I have to disagree with Maggie. I've had my Nissan Micra for 2 years and I barely get 30 mpg. The fuel efficiency was a major selling point for me but I've been pretty disappointed. It could just be my driving habits but I wouldn't rely solely on the advertised numbers.
