I'm really happy with the interior. I like the physical buttons. I'm getting so tired of touch screen interfaces that you can't "feel". It's harder to use while driving, not to mention the interfaces can be slow sometimes. Not disappointed at all...
The new Coyote motor variants are having oil consumption issues. Lots of guys complaining about it and Ford has issued TSB's on it but it's just a nuisance really. The motors are still doing really well. Hell, there are guys making 1000 hp on them. Very impressive motors.
