I bought a 2015 Micra SR a few weeks ago and I am very pleased with it. I particularly like bluetooth (my first experience with it) and the b/u camera. I purchased a manual transmission because that's part of the fun experience. I had a couple of trips to my cottage (240 km one way) and calculated my fuel economy at 43 mpg. There was no problem with the hilly terrain as L'il Red was more than a match for the climbs.
I had the dealer perform a Diamond Kote treatment along with regular spray on undercoating. In addition, I had a spray on soundproofing treatment done and an upholstery treatment to boot.
It's a great little car that reminds me somewhat of a Subaru Justy I had eons ago.
Best...
