    What's This

    Using a top-secret, highly sophisticated algorithm that may or may not have been co-developed by NASA, the Grassroots Motorsports Bang For The Buck Index is a 100-point scale that indicates which of the new cars we've reviewed over the years actually provide the greatest bang for the buck.
