Technical info:

LWO MODEL
Package includes bitmaps, objects (layers) and scene.
All you have to do is to load object from scene without light sources (Lightwave layout). All settings should be loaded automatically.
You can modify quality of model with Object Properties of selected model (Geometry -> Render SubPatch Level).
You can also load model without interior (scene editor - different colour) and change value of transparency of window glass textures.
Lightwave scene includes model with parentage and pivots - it means You can rotate wheels and open/close door.

XSI, 3DS and OBJ MODELS
Packages include bitmaps and polygonal objects with high, medium and low count of polygons.
Door and wheels are separated (movable) parts.

MAX MODEL
Package includes bitmaps and polygonal object. Meshsmooth is applied already and set to '1'. You can modify it to get quality you need.
You can load model without interior and change value of transparency of window glass textures.
Door and wheels are separated (movable) parts.

FBX MODEL
Package includes texture maps and polygonal model in 2 different counts of polygons.
You can load model without interior and change value of transparency of window glass textures.
Door and wheels are separated (movable) parts.
