Get the 1.6
The 1.6 will give you the same (or better) fuel economy as the 1.4 with much more useable performance around town and on the motorway. You have to screw the nuts off the 1.2 to get anywhere, which obviously also hurts economy. Look back in the forum and you will see the same advice - please get the 1.6 or you will regret it later (doesn't cost much extra either).
