Police say thieves took a pair of Bentley luxury cars after they were left with their engines running outside a dealership in Parsippany.
The total value of the two cars is more than $400,000.
Police tell NJ.com that it happened Saturday evening at Paul Miller Bentley.
The cars were running as they were being moved to get away from possible flooding.
They say employees noticed two men get out of a red BMW that pulled up to the store and drive off in the luxury cars.
They watched as all the Bentleys and the BMW were driven onto nearby Interstate 80.
No arrests have been made.
