I'm surprised you guys are complaining about the front of the car...
The rear end looks more like a Camry or Eclipse than anything American. I actually think the front looks nice - I've always liked a forward leaning rake to the nose of a car. My only concern is - for as angled as that looks - if cooling will become a concern because not enough air might be able to enter the lower grill at high speeds. At very high speeds, lift could become an issue.
What I really feel bad for is the aftermarket companies that have poured millions into developing parts for the current mustang only for it to be replaced so quickly by a new body style. Does anyone know if the guts beneath the skin are being changed or not?
