I believe "Abarth" is a term used to describe a performance version of various models, not an actual model. Kind of like "R/T".
Also I find very interesting, since mazda was brought up, that the new Fiat 124 spyder is actually a rebadged miata. I haven't read anything a bout "getting the patent back".
What I can't figure out is why they would farm out a car that is basically the most recognized nodel of their brand.
