I picked up a lookout used from e-bay. Just the basic one, no storage.
It came yesterday and though we haven't had it in the car yet----Milo has been in and out of it. Even got up in it and took a nap.
So I am sure he's going to love it.
He's not a car dog and I had to make a trip back to my NH house this past week---about 4 hours. I rigged something similer to the lookout with a pillow and one of his beds and even clipped his harness to the SB strap.
It really made the trip easier for him. When he got tired of watching out the window he just flopped down and slept.
