Lee Lawrence, who has been selling used cars for decades in the city, says four buildings on his car sales lot have been destroyed, trees have fallen across vehicles and the windows of many cars were shattered when the tornado roared through Saturday afternoon.
Speaking by phone, Lawrence tells The Associated Press he will rebuild. "It will be a start-over deal," says Lawrence, who wasn't present when the tornado struck. "I can't say it will come back better or stronger, but we'll come back."
A photographer for The AP says he also saw antique collector cars at Lawrence's lot crushed by debris and a nearby pet grooming business destroyed amid twisted piles of metal. A printing shop had a pipe spearing what's left of the building and a vacant commercial building also appeared heavily damaged.
There were no immediate reports of any deaths or injuries. Emergency officials have cordoned off the area.

Speaking from the weather service office in Jackson, Mississippi, she added that a team of experts would be heading to Columbus on Sunday to determine the storm's size and strength.
