The data presented in the dashboard can be viewed with different perspectives. On Most pages (except the Executive Summary) you will see a flay out menu on the left of the screen market Filters. 

Clicking on that button will give you a number of options, presented in three groups.

Vehicle Types

By default, both new and used vehicle sales are used to calculate performance. By excluding one or the other, attribution for the chosen inventory segment will be shown. (Segmentation does not apply to Cost Per Sale metrics and cannot be used on the ROI Audit page).

Sales

By default, sales data from all rooftops in a single group is used to calculate performance. This means to if a buyer interacts with a marketing tool provided by any store in the group, that touchpoint will be included in the reporting. 

In order to see results for a single property, the best practice is to click the Exclude button, and then choose only the subject property.

Third Party Auto

By default, attribution is shown using both sales associated with leads and phone calls, as well as sales that occurred after the buyer had visited the marketplace websites. Excluding the website traffic will result in attribution shown for sales from leads, which will be fairly close too the data in the CRM.
