COSTA MESA, Calif.-- launched this week an online side-by-side vehicle comparison tool, the National Automobile Dealers Association (NADA) reports. The tool will give consumers the ability to compare up to four different vehicles simultaneously. It allows consumers to compare new vehicles against used vehicles that date back to 1998. Vehicle buyers may now handpick the vehicles they want to compare side-by-side, or they can choose to have select a 'recommended' list of vehicles to compare. Chrome Systems Corp. powers the 'recommended' list. The 'recommended' feature automatically provides a list of vehicles with similar designs, pricing, features and specifications, the organization says. In addition to pricing information, the comparison tool provides consumers with a chart of detailed information for each vehicle, including powertrain data, fuel economy, cruising range, engine type and displacement and more.
