What Does "Reasonable Offer" mean?

here is the one that gets me most. And this happens. Somebody approaches one of my classics and asks how much? Mind you, it's not for sale, wasn't advertised, just my vehicle and they decide they like it. I shoot them a high number because it's "not" for sale. They proceed to tell me I'm out of my mind, then offer not even a fair price. Then I remind them "it wasn't for sale, but you wanted a price and you got one". Now, I just tell them "it's not for sale, so offer a price and see if you like it more than me". Usually, they don't offer just walk away.. and if they do offer (usually not even fair price) I just say "I guess I like it better than you" .. lol
I had that happen to me once. I had a semi-restored jukebox that a friend of a friend heard about via word of mouth. Said jukebox wasn't for sale, as I still had some bugs to work out on it, but when I crossed paths with these two at a show, I was asked, "How much for your 1448?" I told them it wasn't for sale, but you know the drill, and they kept pushing, so I "upped" the price in my head and said, "$8,000", thinking this would shut them up.

Nope. Guy pulls out a wad of cash and starts counting it out, so I had to "put up or shut up".

And I did....while laughing all the way to the bank!
