At this point, what can I do? I would like to work this out so I can go

Yes, decide exactly what remedy you want, and have a lawyer send a
nastygram to that effect. This dealer/mfr is an expert professional at
evading responsibility, you are just a dabbler at enforcing it.

If it's not worth hiring the lawyer, then you really don't have enough of a
gripe to be worth pursuing.
