They are gorgeous.
I would belt them in with a harness. It just became the law in Maryland, but I have always done it since dogs can be injured if thrown against the crate (which Lucy doesn't tolerate well) or left as a potential projectile, but what really terrified me is that someone said if I were in an accident and became unconscious and she tried to protect me from emergency responders, they wouldn't hesitate to shoot her, so she gets belted in.
