As I mentioned earlier, don't buy the Camry Hybrid. Get the Nissan Altima Hybrid instead.
The Nissan Altima Hybrid is essentially the same car as the Camry Hybrid, using the same exact Toyota Hybrid Synergy Drive system as the Camry Hybrid, which Nissan licensed from Toyota.
The main difference is that Uncle Sam will pay you $2300 to buy the Altima Hybrid. http://www.irs.gov/irs/article/0,,id=176409,00.html
You get $0 Federal Tax Credit for buying the Camry Hybrid. Federal Tax Credits for Toyota hybrids were phased out last year.
