Im to the point where if its a black grill, I'll probably just pass unless its super clean physically with no chips in the kettle or bowl. If its that nice, I know I can find someone that could use it.
Example, this weekend I was at an estate sale. I saw 2-24 lbs of Kingsford that wasn't even in the "sale area" It was off to the side in a spare shed on the property. The seller actually told me I could just have the charcoal, I even offered money for it, but they refused. I asked do you have a charcoal grill somewhere? I never saw one anywhere in the garage or yard. He said, "well actually yeah, but it so old and beat up, I don't think anyone would even want it" I said, "how old?" He said, "oh, 30-40 years or so" Naturally my curiosity was peaked, so I said where is it at?
He took me to another spare shed and showed me. It was a faded black/greyish "B" code. Metal bowl handles. It has the average "battle scars" and the lid handle was bent off to the side, it had 2 of 3 leg sockets broke off, it was missing 2 of the daisy wheels also. The wheels were the newer style still that we are all used to, and it had the rolled edge ash pan held on with clips. It has no special parts even worth taking. The seller wanted to give it to me and even LOAD IT IN MY CAR. I still passed, but felt guilty as I walked away for leaving the grill there in the shed, knowing what its ultimate fate would probably be.
Now if its a colored grill, I don't think I would pass on it unless it was chipped up to the point were I just couldn't look at it. Chips on the lid REALLY bother me since I have to look at it every time I cook on it. There is always someone that wants a grill of color if it doesn't need much work.
