... Footage of frontal impacts concerning this anchoring system look good, but no side impact testing as far as I can tell...
Yes, I think all that stuff is well sorted out for frontal impact. Even the cut floor minivans like to show you how they fare in front or rear impact. But you see no mention of side impact. With all the floor structure moved well below the frame or main bumper supports of other vehicles an no side impact beams, I can't imagine the protection is very good.
Up close, the MV1 looks very impressive structurally - probably as stout as the H1 Hummer's that came out of the plant. Too bad they are so expensive and lack versatility. I've corresponded with them pointing out that it doesn't even have a fold-down rear seat so I can use it to haul lumber or plywood once in awhile. If they could at least do that, and put a modern 6spd automatic in it, I might be willing to pay the price.
My frustration with the Promaster pricing, ($10K more than a minivan with all the same powertrain and NO interior or rear heat and AC provisions), lackluster inventory (95% is clearly targeted at basic delivery) and endless wait to even see a Transit, has me looking seriously at a Caravan. You can get an SE with the 30th anniversary package (pretty much everything but power seats and leather) for $20K with current incentives.
For $10K less I can build a custom wheelchair solution. Thinking of a shuttle seat with fixed foot supports. If you've ever seen the huge bins in the floor for the Caravan stow and go seating, there is lots of room for the foot supports of full rehab seating system. I think it's about 54" of total vertical height. You just need a system to transfer the seating system from the powerchair base to the interior of the vehicle.
I actually despise the US rehab industry for perpetuating the idea that we need to spend $20K or more every 10 years cutting up a perfectly good vehicle (making it rust much faster) to transport a very dumb wheelchair. They've had better systems in Europe for over a decade.

Unfortunately that chair isn't even made anymore.
