Can 2006 purchase be claimed on 2007 taxes?

everyone. I've been a lurker on these boards but am now coming out of the woodwork to ask about the notorious Hybrid Vehicle Non-Credit.

First, some background:

My husband and I were severely affected by Hurricane Katrina. We lost all the contents in the house that we were renting at the time, and our insurance did not pay anywhere near the amount that we had lost. We also lost both our vehicles, for which our auto insurance paid pretty fairly. Once we got our checks from Liberty Mutual, we decided we would buy a used small SUV for hauling around equipment to be used in rebuilding our home (we're buying the same house we were renting from my father before the storm) and my husband's business, and ordered a 2006 Prius, which we actually purchased in January 2006 (time-wise, we would have been eligible for the full credit). "Doing the right thing" was my main motivation for wanting a Prius, but my husband's was the fuel savings and tax credit.

As it turned out, my husband's business took very long to reopen, and he had no income until December. Meanwhile, I was employed in a predoctoral internship program at a VA hospital (I started the program 2 weeks before Katrina hit), and my income was next to nothing. Basically, we were living on our savings all year.

So, now, as we try to do our taxes (and, BTW, I didn't wait this long to file out of procrastination, but rather because the VA had never sent my W-2, and after many, many phone calls, only on Friday did I learn they had been sending my forms to an address that does not even exist), I find out that we cannot receive the credit because we did not earn enough or withhold enough tax to receive the credit in the first place. Furthermore, the "Why the difference?" pop-up on TurboTax indicates that this credit does not carry over to next year's taxes.

Now, this year (2007), I have a lovely consulting contract with a large corporation, my husband's business is (knock on wood!) picking up, and I anticipate owing the IRS big-time next year.

So, here's my question:

Is there any way that I can wait until next year to claim my credit? Or is there any other creative way to take advantage of the credit?

I have come to terms with the idea of not getting the $3150 or whatever, and I certainly don't want to cheat on my taxes. However, if there is any way to work around the issue, I'd love to learn about it! TIA for your advice.
