Matter of opinion. If you wanted one you will pay for one. Thankfully we had our original 67 am/fm came with car. Dont ask what we paid to have it refurbed. I'll say/ask again, show me ONE listing for an am/fm for $10 lol.
Rusty??
Agreed, it's a matter of opinion. And some people will pay prices for things that make no sense at all.
As for professionally refurbishing an antique radio, that's a different story. Nobody did anything to this one except photograph it and post it on eBay. Didn't even "test" it.
Looks rusty to me. Matter of opinion maybe. Besides, it's a figure of speech.
