Smart for two, Mercedes-Swatch concept, newer model from 2007, comes with fully modeled interior and textures. It is modeled according to original plans with precise details. Car materials are included and easy to change.
Two .obj files contain lowpoly and hipoly models, separated by material and object. Both are tested in 3dmax 2010, Modo 401 and Blender (might require additional smoothing or triangulating while during import). Other formats also import properly in their native software.
