Holy smokes!
Thinking I would be helpful, in case someone else needed a tow bar, I thought I would go searching for them and post a link.
what I found was that even a simple tow bar like mine, that doesn’t even have a fancy lever to spread it, is selling used on eBay for over $200.
As I recall I paid about $30 for mine, new, in 1997.
I guess we should have purchased a bunch of tow bars and stored them as a retirement plan.
