An advanced search permits more information to be used to filter possible matches, reducing the results but increasing the chance for a suitable match. This search offers not only the basic search information, but additional fields, such as dealer code or location, as well as more specific vehicle information. Some fields are "smart," such as when a specific make, the corresponding model list is automatically updated to show just the models for the make selected.
While users need not have information in every field, the fields are there to help users refine their search so that it will return a likely match. For more information, see searching tips.
