This model is a highly detailed golf cart, modeled after the popular ClubCar Precedent i2.
In the 3ds Max file, the model is a single editable poly object, so merging this into your scene is simple plug and play. Materials and textures are already applied. For the other exported formats, the model will import as a single object as well. All objects and materials have sensible, descriptive names.
Textures are included in a separate ZIP file. The .OBJ format contains its own set of texture bitmaps (included in the OBJ zip) so it should import needing little or no extra attention.
Model created with 3dsMax 9 and rendered with Vray 1.5 SP2.
