I figured the classic car crowd would pay to keep the cars original, guess not.
They will, but the demand for R12 is terrible.
I worked for an HVAC wholesaler for ten years. We had two 30 pound drums of R12 and would weigh the drum when it left and when it came back and sell it for $30 a pound. We might have sold ten pounds in ten years.
So yes we got $30 a pound for it, but it wasn't flying out the door. It was discussed that when we ran out we wouldn't order any more.
Also, I looked and they have 250 thirty pound drums of R22 in stock at just under $800 a drum. There are fly by night web sites selling R22 for $300.
