With gas prices on the rise, and energy policy in the headlines, both consumers and governments have reason to be happy about GM’s new hybrid, the Chevy Volt. The car is still in limited supply, and it’s pretty expensive — near $50,000. But for those who can get their hands on a brand new Chevy Volt, the government has added an incentive — a tax rebate of $7,500. However, as Mary Chapman writes in The New York Times "Wheels" blog, that deal may have been a little too sweet. Car dealers across the country have begun snatching up the rebate for themselves, and leaving their customers in the dust.
