As the flooding spread, so did the chaos - leaving tow trucks to retrieve cars abandoned in the middle of the street.
Maria Florio says she barely moved her vehicle to higher ground in time - minutes later her garage and basement had flooded too.
"It was basically hysterics, basically you didn't have time to be scared," Florio said.
The car dealership is near the Peckman River, where cars ended up submerged in the water. A towing company owner said about 16 cars had been removed from the river by Sunday morning.
Emergency responders say much of the recovery will be a waiting game until the flooding recedes.
