Unfortunately, I have not heard of many that have made it to the US in period.
When I visited West Allis in 2009 I was shown a picture of a fully grinning prowd new owner standing in front of an open 20' shipping container that contained the AC Petite, Nobel 200, and a Messerschmitt. At that time the picture looked to be at least a couple of decades old.
The cars were all basically longitudinally oriented, but the tapered ends of the Messerschmitt and Nobel faced each other and the vehicles were both canted and offset from centerline of the container's longitudinal axis- this plus the narrowness of all 3 cars allowed their combined length of approximately 30 feet to be accommodated in the 20 foot container that was shipped from England.
I used a similar strategy a few years later to bring in what turned out to be Nobel 200 parts car, Frisky Family Three, and Trojan 200.
That success emboldened me to hatch my plan to some day find eight Sans Permis vehicles short enough to be fit sideways in a 40 foot container. After 14 months of frantic searching and emails I realized that dream in 2015.
Now the last load of eight is accommodated in a longitudinal tandem orientation in a 12' x 32' long end section of my barn, and I am about to petition my city to hopefully become allowed to lengthen my barn another 20' to become enabled to get it to contain the greater percentage of my collection.
Most of the cars are unfinished projects, and I do good work, but very slowly. As it turns out, I am now finally enjoying the process of coming up with creative solutions for getting everything that is not a vehicle off of the barn floor so I will have greater access and space to enjoy the views of my unusual lots.
Most rewarding solution so far has been my deciding to store a large pile of long unused antique redwood floorboards in the rafters, thus creating storage space for many more lighter wieght items without blocking ambient lighting from the 4O' x 2' long skylight that I created by replacing the rotted sections of corrugated galvanized roofing panels with very hard to find translucent fiberglass roofing panels with identically dimensioned and spaced corrugations.
I still have about 100 of these 3' x4' 40 year old panels that have never seen sun, but we're intended for green house use to find space for. So I will continue my project of replacing the remaining 5 of 8 solid metal windows with 4 panel thick stacks of them, and then hopefully find a way to tuck the large number of them remaining up inside the perfectly matched corrugated surface of the barn's interior walls at a height that keeps them off the floor so as not to unnecessarily consume more useful interior wall storage.
I'm nearing retirement, but will certainly never have want for things to do.
