Little update to add...
-engine damage enabled
-moved rainfx enabled data.acd to 'rainfx_data' folder, car is vanilla (ish) to start with, replace the data.acd with the one in the folder if you want RainFX. Probably should've done it this way to start with, should work out of the box for everyone now, and people who want rainfx are hopefully a bit more likely to read the instructions.
-reduced lod A tri count a bit
-reduced lod B tri count a lot
-added lods C & D
-added a couple of skins to celebrate the start of the football season. Hello false hope followed by crushing disappointment, my old friends
-darkened the tyre texture a bit
-various little tweaks to the model and data (ie. I forget what I changed)
Have fun, let me know if I've missed anything or if you have any constructive criticism.
