I thought it was pretty self explanatory.
I made it.
NFSCarbon has a feature where you can take screenshots of your cars and they automatically upload to the internet, along with what performance mods you have on the car at the time you take the picture.
It's a Vauxhall Monaro VXR. I tried to make it look as much like a GP as I could.
The game has endless customization. You can fiddle with the aftermarket stuff, tweak everything; how deep the recesses are in the body parts, how big the grill is, how far everything sticks out, how big, tall, wide the parts are, etc etc so on and so forth forever.
So that took me awhile. Lots of tweaking.
