I think it's OK naming. The Germans and now Cadillac have gone with letters and numbers. It does make is simpler. This is a riff in that the last four letters gives you the body style. Granted you have to know what the beginning letter stands for, which is not ideal, but the convention isn't devoid of reason or impossible to follow.
I can see the attraction of getting rid of a vehicle. Perhaps the Cadillac XT4 will be large enough? The electric range should be low 30s. Supposedly it's not that much smaller than the XT5.
