He's a douche bag threatening to get a lawyer. I won't hold my breath for news that suit has been filed.

There are very well established rules about this and they go back to the beginnings of mass print media, long before people could sue at the drop of a hat. The general rule is that you can't do bait and switch - deliberately advertising an artificially low price and then pulling it back when people come to look. Most states have laws making auto dealers sell for the advertised price. But there is a well established exception for obvious mistakes and misprints. A typo one decimal place off is the classic example. He's just trying to get a freebie. No one will pay any attention to him.
