LWO (6)

Package includes bitmaps, models (parts separated into layers) and scene with pivots and parentage (rigged) so you can rotate wheels.
All you have to do is to load object from scene without light sources, all settings should be loaded automaticaly.
You can modify quality of model with Object Properties of selected layer (Geometry -> Render SubPatch Level).
You can also load model without interior and change value of transparency of window glass textures.

Polygon / vertices counts:
subdivision=1   -   89599 / 108724
subdivision=2   - 235203 / 235864
subdivision=3   - 479639 / 501549

3DS

Package includes bitmaps and polygonal model with high, medium and low count of polygons.
Wheels are separated (movable) parts.
Interior is separated part.

Polygon / vertices counts:
hi-poly            - 965794 / 505353
med-poly          - 480344 / 257320
low-poly          - 189074 / 107528

OBJ, XSI (3.5)

Package includes bitmaps and polygonal model with high, medium and low count of polygons.
Wheels are separated (movable) parts.
Interior is separated part.

Polygon / vertices counts:
hi-poly - 479639 / 501549
med-poly - 235203 / 235864

MAX(5)

Package includes bitmaps and 3dsMAX scene with low polygonal model - meshsmooth is applied already and set to '1' - you can modify it to get the best effect.
You can also load model without interior and change value of transparency of window glass textures.
Wheels are separated (movable) parts.
Interior is separated part.

Polygon / vertices counts:
meshsmooth=0   -   89599 / 108724
meshsmooth=1   - 235203 / 235864
meshsmooth=2   - 479639 / 501549

NOTE: The model was made and rendered with Lightwave, other formats may need some work on materials.
