I have converted that car... replacing the Veloci.
I think you had that annoying damage texture problems.
Also i use the improved cars from revisited v5, they look better.
I take the cars from the mm2core and the improvements from the revisited v5 maincars file.
Now the hardest thing is to place the lights...
Here are some tutorials, they can help you in placing the lights, if there is a tutorial.
