Hybrids sales soar despite long payback.

Even with a hefty tax credit, Jerry Brimecombe understands that it could take as long as 10 years to realize a payback for buying a hybrid Toyota Camry. While fuel efficiency was important, concerns about the environment and lessening the country's dependence on foreign oil entered into his decision to buy the car 16 months ago. "I think it makes sense to have a hybrid, even if it costs a little bit more," he said. "Sometimes we have to make decisions that are better in the long run."
