The 1.5 is the best choice.
There is an ongoing battle with one owner who bought a used 1.0l Civic 10 and the engine has been destroyed, out of warranty, because the timing belt, that runs in oil, snapped.
Also on the MK10 make sure the aircon pipe has been replaced, or it whistles, and the front bumper has been replaced, or when it rains, the front parking sensors fire up. Both replaced FOC on complaint.
