On Change of the drop-down, keep the action set as "Refresh this Section" and inside it call a Data Transform.

In Data Transform, do a property set for Style and Make with values from Data Page, by passing Vehicle ID as a parameter to the DataPage.

For Data Page, you can use D_CarRentals data page which will be created for Data type if you have selected while configuring records.
