The "I'm overseas right now, the price is right, I'll send money and have my agent pick it up" really bother me. It's like there is a script they all use. Then there are the trade ones, like "I'll trade an i-phone and i-pad for your bike", or even better, "I'll trade you two lizards - your choice from the following list" are the ones that get me. Finally there are the "Will you finance?". In a word, NO!
So the lowballs are just part of the game, and easily ignored. At least they define a bottom line for you. In my case, if I don't get what I have in mind I'll just hang onto the bike, and consider laoinging it to my brother or selling it to my niece in a couple of years when she gets some $$$ scraped together. If I'm going to be charitable about it, it might as well be to someone I know.
really?
