Howdy,
My beloved Geo Prizm has gone to the caryard in the sky, which means I'm going for a 2006 Civic Hybrid.

There's a dealer here that has one coming in in the next few weeks. I'm willing to wait until January 1st to pick it up to take advantage of the tax credit.
Having said that I'm having a difficult time finding anything official that says that if I purchase a hybrid say tomorrow, and I pick it up after January 1st, that I'd qualify for the tax credit. Does the transaction officially take place on the day I drive it off the lot or when I sign the paperwork? Where can I find something that confirms that the transaction is based on the day of drive-off? I've read about folks who are doing this, but I'm hesitant to gamble with that sum of cash based on hearsay.
Your help would be greatly appreciated,
Jeff
