Have you heard about a deal to get as much as 38 percent off on a Tesla Motor's Roadster?

Apparently, the offer is real. If you live in Colorado.

The state is offering a tax break that could allow you to own a $109,000 Roadster for $67,800, according to GreenCarReport.com.

"The measure gives Colorado residents a credit on their 2009 income tax for up to 85 percent of the difference between the price of certain alternative-fueled vehicles and the price of an equivalent vehicle running on liquid fuel," the website said.

That means the tax credit for a Roadster, a sporty two-seater, is about $42,083.

Granted, the incentive doesn't make the Roadster an affordable car for average households. So Tesla isn't likely to see a huge jump in orders from Colorado.

The San Carlos, Calif.-based automaker is due to launch a cheaper model priced starting at $57,400 (without any incentives) in late 2011. The company hopes to attract a broader base of customers with the four-door sedan, the Model S.
