This is a Live for Speed car 3D definition CMX file importer.

I spare you from the usual disclamer, you know the lyrics

It can work on Blender version 2.62, maybe lower (I'm too lazy to check that) but certainly not higher since the next version has a non working Python API.

To install it, run Blender, go to "File" > "User preferences", "Addons" tab, "install Addon" button, point the io_import_scene_LFS_cmx_262.py file you extracted somewhere on your drive. After validation, check the "Import-Export: Import Live for Speed car (.cmx) Blender 2.62 compatible" line, and tick its case on the right to run the addon.

To make it run each time you open Blender, click on "Save As Default" button.

Then "File" > "import" > you know what's next In the file picker dialog you have the option to create dummy LFS-like materials for the model. This loads LFS Viewer's textures and applies automatically the materials on the model.
The second option imports the model's vertices' colors.

If you've read this until here, good luck, you have so much to learn about Blender and 3D modelling

Have fun
