There are a few companies who make hitches that will work with the Element.

Curtis, UHaul, and Reese.

I can't remember which one it is, but one installs with no extra drill points or special mounting, it uses pre-existing holes in the frame.

Honda's isn't bad but remember it's a Honda accessory so it costs more than it should. If your set on the one from Honda, try College Hills Honda's website they have a very good parts/accessories site with excellent service and discounted prices.
