Interesting cars. I have ridden in a car in the US with passive seatbelts like that, part of it moved on electric motors when you turned in the ignition. More recently when I went there the hire car wouldn't start unless you had put on the standard type belt - far cheaper to install I would think. I can't imagine that the Montego engined car drives much like a Landcrab, different engine, gearbox (I assume) and suspension.
I agree, it's not what I would choose, but it's an interesting thing. I forgot, but apparently you undo a few bolts and the entire front comes off, so there must be a space frame structure in there. Pics 4 + 5 show a plug in the bulkhead top left, pull that and the front panel structure just lifts away as one.
