The most important thing to think about here, would be the safety aspect now, and down the road.
If it got damaged in this wee car or even on a truck,
and propped up by other methods, probably very likely to happen, with some designs....
it could be a dangerous affair!
Price that into the list, I mean by that
in, maybe refusing to agree with the clients design, and not doing it the cheapest way possible...
He could have his own ideas by now to add to the mix.
