It looks good to me but this strikes me as the kind of thing where the devil is in the details. I wonder about the clearance between the rear trike wheels and the ground. There's a potential "yucky seat" issue too.

I'd want to see one "in the real" and see how it fits my car and how my trikes fit on it. I might call a recumbent specialty dealer, like Hostel Shoppe or Utah Trikes, and ask what they know about the product.
