Wow...this is pretty cool...

"Starting in 2006, the Energy Tax Incentives Act of 2005 provides for some pretty nifty incentives for fuel efficient vehicles:

You can get a fuel economy tax CREDIT (not a deduction - a credit) of up to $2,400 for a car that gets 2.5 times the milage the comparable model got in 2002, or up to $400 dollars for a car or light truck that gets 25 to 50 percent greater milage than the 2002 model."

This is of course good news, it's to bad that they are delaying it all till 2006! But whatever, the funny thing is that the best tax breaks are for cars that don't exist, and that wont exist in large numbers for the next 30 years.
