I received a really rude and inappropriate email. What do you think of this?

Tell him its you. Then tell him I'm not going to sell the laptop to you. Useful lesson.

If he keeps emailing you, there's a blocking feature on Yahoo! that can block any incoming emails from a certain address.

Block the kid's email address.
Besides a 16 year old, is just that, a kid.
It was good you didn't wrote anything back to him, it would made things worse.
You're a young adult so you don't have to put up with a rude kid. Ignore him. Block him.
