Thanks, niky!
Fuel economy-wise?
Well, I saw 48 mpg US / 4.9 L/100 km
in the manual Mirage in my shorter drive which was 100% urban (not mixed) and in much cooler conditions.
I suspect the Mirage would have returned in the mid/upper 50's mpg US (low/mid 4.x LHK) in the same conditions as the Micra.
I'm actually hoping to be able to compare the two cars back to back at some point this summer.
