I Inherited my azure blue 2013 Jazz 1.4ex last year when my Dad passed away, and although its not my sort of car, its not a bad small hatch for shopping and days out etc...
the economy over winter on very short trips can be as low as 30mpg.and on a run high 40's.... but ive fitted a k&n panel filter,for improved air flow, and i use shell v-power nitro plus fuel,(dont laugh!) and today went on a gentle drive, (cruise control set at 58mph) and i got 58.8mpg! so if you drive like a vicar they can be economical! lol.its just coming upto 3 years old and has done only 6,000miles!! just wish it was faster
