So, I am impressed by the engine and even how Ford have tuned the suspension, despite the continued use of a beam axle. Nice splitter. Graphics are fitting.
But the interior. Ugh. Too much plastic. The Alcantara feels good on the seats but the Alcantara on the steering wheel is spoiled by the plasticy feeling bits on the spokes. The dash looks pretty cheap and the door panels are just ugly.
I can see why they can deliver so much performance for relatively little money. The Audi TTRS I sat in was much nicer. I could see much better out of it too. The Mustang meant I had pretty much zero ability to see a car in the lane I would be changing into. Huge blind spots.
As for the GT500, overinflated and ugly. Even if it has 650hp I still don't want it.
On the plus side the Ford display was better than Porsche's this year. You could sit in the cars, they had engine parts and cutaways all over, and the dyno run. Porsche had the Boxster Spyder locked up.
