Very cute. Lots of ideas in there. Cool use of permuteArgs. And a MIC!
Doesn't handle strings with quotes or escapes, but that's easy to fix if you
don't care about performance of that case.
Re-entrance detection is too strict, I think; looks like it would fail if the
Car had a Wheel.
You could build a templating engine by factoring out the middle parts of it.
That could then be used to create the JSON dumper.
