"I'm just an honest car salesman. Seems like you just don't know who you can trust these days."
―William Dewey

William Dewey is a character in L.A. Noire. He is the owner and proprietor of a Packard dealership named Dewey's Car Sales.



Dewey met Argentinian Consul General Juan Francisco Valdez at a bar. Dewey offered Valdez a substantial bribe to purchase a Packard from his dealership. Valdez accepted the deal. At the dealership, Valdez became infatuated with one of Dewey's mechanics, Gabriel Del Gado. However, this would only enrage Gabriel.

Detectives Cole Phelps and Stefan Bekowsky investigated the car, which had ended up in Oswald Jacobs backyard. At the scene, Phelps found a wrench that belonged to Dewey's dealership. Once at the dealership, Dewey lead Phelps and Bekowsky to the garage, in which they found out that the wrench at the scene of where Valdez's Packard was found belonged to Gabriel.
