The Materials in Revit have changed drastically since then--using Mental Ray Protein 2 materials.

You will need to upgrade each family, and assign material parameters, then load into the project
and assign new Materials.

cheers

Those cars were set with accurender materials, you'll need to as the previos poster noted open the car and under the imported categories, you will see that the material is assigned per layer. Once you've reassigned all the materials, please upload the cars to us so we don't have to do it too:)
