America has the hots for hybrids. On the flip side of high gas prices, the value of any vehicle with fuel economy below 20 mpg has collapsed. Brand new "gas guzzlers" sit on dealer lots collecting incentives, rebates, finance deals and dust. The price of used fuel-suckers has dropped by 25 percent in the last four months, and THEN the rest. This is the perfect time to shop for a twin-turbo twelve-cylinder behemoth.
