According to Compete-
Does the price of gas actually run the engine of automotive interest in the US? If you sell compact cars it sure does. Compete tracked monthly shopping, or demand, for the compact car segment and compared it to the monthly U.S. weighted average gasoline (all grades) prices over recent months. Compete measures in-market demand by looking across all popular 3rd-party sites and aggregates unique shopping behavior by observing how many people actually utilize shopping tools for every make and model.
