About 12 years ago I saw a MB Vito van I'm Germany with the Westfalia treatment. It was really nice and I was strongly lusting after it. At the time the dollar was very strong and was seriously looking into importing one, but it would have been too much of a hassle.
I was just looking at the Ford Transit Custom which is of similar size. With long wheelbase and high roof it yields about 5'-10" headroom and about 210 inches long, which would fit in many garages with 8-ft-high door.
I'm pretty sure Ford won't bring a third "Transit" van size to USA but the possibilities are interesting to consider nonetheless.
