What is "low ball"


A lot of ads say something to the effect "no lowballers please". So I'm curious what people think is "lowball".

I'm looking for a percentage from people. I'm thinking less than 75% of asking price is where "low ball" kicks in, but I'm interested in what the general consensus is (if there is one).

I'm going to Wanted to Buy section. Maybe I find someone else willing to sell.
Is this lowballing or just the "Art of Negotiation"?

Guy: “If I gave you a million dollars, would you sleep with me?”

Girl: “A million dollars is a lot of money, and you don’t look that bad, so I guess I would consider it”

Guy: “Ok, since I don’t have a million dollars, would you sleep with me for $100?”

Girl: (outraged) “What kind of girl do you think I am?”

Guy: “We’ve already established the answer to that question. Now we’re just negotiating the price”
If I bought a car I would know the price I could realistically get it for when I arrive. It's called doing your homework. I guess getting offended one time out of the many negotiations I have had should immediately diqualify me from participating in them any more. I just avoid the bottom line question and ask the buyer to make an offer. It's funny that you found my, and others, taking offense offensive yourself. I mean you found my initial comment "so foreign to me that I don't know how to respond." Yet you did and have over and over. It could be inferred from your logic that you shouldn't participate in this type of thread anymore. AMEN!
AMEN! You make sense, but if he stops now the funs over. Cars take some homework but it's well worth it.
