Thought I'd update this thread in case anyone 'googles' for the same information that I was after - pictures of the Twin Air in Crossover black with the 'Pack by Abarth' option.
After a very long search (with little help from Fiat UK) I found what appears to be the Dutch version of Autotrader..

Inbetween the 'proper' abarths there are a number of Twin Airs with the Abarth Pack option in both Red and Black. I've come to the conclusion that I prefer the red I think.
While most likely be placing an order for a car in the next couple of and although I've haven't settled 100% on the 500, its the main contender. And if I do end up with one its a good chance it'll be in the spec as the car appears on the first page of this thread
