Tough, in my area we don't get many Guidos. Thats more of a Seaside / South Jersey type thing. In Central Jersey we get a lot of Bennys. There is a difference believe it or not. Guido's are like these guys
http://www.guidofistpump.com/guidos3.jpg - probably coming from northern New Jersey. The Benny comes from the New York City area and Long Island - drives a giant Mercedes, does not care if the light is red, does not care if the person has the right of way and makes a left turn nearly causing an accident, gives you the finger for your high beams while in actuality your using your low beams, drives into the wrong lane from 3 cars back to cut you off while your trying to make a left turn waiting for the oncoming traffic to pass - nearly getting everyone into an accident, ect ect. Benny's love Deal, NJ. Benny's are typically Syrian Jews as well, where as Guidos are typically some obnoxious Italian guy. But these terms are definitely interchangeable
