According to The Recorder, hybrid cars may not be as great as we all thought. The additional materials required to make hybrid cars (in particular, production of the nickel used in the large batteries) is terrible for the environment. That, combined with a shorter expected life span, may put the Toyota Prius behind even the mighty Hummer in environmental damage.
In the spirit of full disclosure, I would totally get a hybrid - it's seems like the cheaper way to go. Although fixing it when it breaks down might not make that more cheaper.
