Selling a car seems to be so difficult!!

Well, there you have it.

If someone is trying to sell a car, and asking $6500,
making the statement that you wouldn't pay more than $2000
(without even looking at the car) is insulting in my opinion.

I know the dude asked for opinions, but again, $2000 without even looking at it? I don't think he's being thin-skinned. Wouldn't it have been better to say something like, "I would pay much less than you are asking"?
