As far as I can see, the photoshop images, the mockup and, in all liklihood the actual car are based on the Fiat Bravo. For me, this is a good thing

It looks almost exactly like a Bravo and it would stand to reason that Fiat would re-use it's platforms & other components across the range, VAG-style (Skoda > Seat > VW > Audi).

I'm looking forward to it!
