Classifieds - e-mail alert?

[Simpo Two]

Greetings clever folk,

Is it possible to set up an e-mail alert, such that if/when a car you're looking for is advertised, you get an alert, thus saving having to go back and look every day?

That's the thing! I hadn't noticed 'e-mail notifications'; I guess I was looking for 'subscribe' or 'save this search'.
