None taken.
Being as pretty much anyone I associate with out side of my work owns or has owned a Buick, that would be the way I would generally proceed. I am not generally a seller though. And I make it a point to know what I am buying so I don't have to depend on a seller to know what they have. I find this is the best way to get those bargains.
I stand by the sell to those who have my money. If you get stiffed enough, I have found it better to have the cash. Though, situations vary, so a worked out trade works good too. Make it a win, win.
