as for holding up, I have a good story -
My fiancee and I went to visit her cousins. As we were driving along, a truck on a side street caught a power line, and snapped a supporting telephone pole on the other side of a cross-street in half. The upper half of the pole proceeded to fall directly upon my fiancee and my heads (in the back seat of the escape).
The roof was crushed, and another few inches and the pole would have been on my head, which was nearly touching the roof.
All in all, structurally, the escape held up quite well and I am very happy it did!
