On Hybrids and the planet

There a lot of hype about purchasing a Hybrid vehicle to help save fossil fuel and lessen toxic emissions. But if you really want to help the planet: buy secondhand. 50% of the energy an automobile consumes is in its manufacture. Though only 10% of the lifetime of a vehicle's toxic emissions are involved in the manufacture, I believe it's still better for the planet if you buy a used regular gas engined vehicle!
