I think XT1032 is an original Moto G that can't do 4G. The 4th gen moto G just got released, the old Moto G will be on minimal firmware support by now so stuck on Android 5, so that ebay deal doesn't seem that good.
The new one:

If you like the size of the old Moto G, take a look in Tesco at the latest Moto E as it is pretty equivalent spec to an old Moto G. I think you lose a few pixels on the screen (I can't really tell) and the front facing selfie camera. Wait a few months and a 3rd gen Moto E will probably be out now that the latest Moto G has already been released.
