For the third straight year, the 2007 Daytona 500 ended with a green/white/checker finish. With a multi-car accident beginning while Mark Martin and Kevin Harvick raced to the checkered flag, NASCAR held off a field-freezing caution flag. Martin was ahead at the time of the accident, but Harvick edged him out before crossing the finish line; the official margin of victory was .020 second, the closest Daytona 500 finish since 1959.<br>
