From NBC's Tom Costello and Domenico Montanaro
The "Cash for Clunkers" program deadline for dealers to file for rebates has been extended until tomorrow at noon ET.
The reason: The Department of Transportation's "Clunkers" filing Web site went down this afternoon.
Tonight's 8:00 pm ET deadline for any sales made stands.
The DOT said there was "an overwhelming demand on the CARS computer system. ... Despite a large increase in the system's capacity, the website was down temporarily this afternoon. Because of the temporary shutdown, dealers have been given extra time to file the necessary paperwork."
