My thoughts are similar. The B Max is a great car and the 1.0 turbo is much better than the 1.6 but not available with an auto box. If you really need an auto, ensure it has the replacement clutch pack or go for another make. Fords auto boxes seem to have lots of issues.
I've done 26k in my 1.0L 123 bhp BMax and it goes like a 1.6 but averages more than 46 mpg. Only problem so far is a brake lamp bulb blew a few days ago, which I replaced myself as I had a spare and couldn't be bothered to go to the dealer.
B Max Titanium X 1.0 125 bhp in Magnetic with built in SatNav and rear sensors.
