Locking Gas Cap for H3 Base?

[Mr Hank]

Hey all,

With gas now officially well over $3/gallon I'm sure the days of stealing gas from siphoning (did I spell that right?)are now upon us. I'm sure many of the less upstanding citizens will start to look at H3 like the local BP station.
Is the a standard locking factory gas cap available?

I was reading a ways back that the H3 as well as many other cars has an anti-siphon thing-a-ma-bob http://www.elcova.com/infopop/emoticons/icon_wink.gif

Every GM vehicle made in the past few years has an anti-siphoning valve at the bottom of the filler neck. There is a cone shaped tool that you can put onto a hose, to bypass, but your friendly neighbor kids won't have one.
I can't verify that the H3 has one, but I can't see why it would not when Saturns, and other GM vehicles have this device.
