The Norwegian police force actually drive Wolksvagen Passat’s, but since there are no Passat’s in Forza 5 I recreated the paint on a rather similar car when it comes to appearance. The Audi RS 4 Avant. On the actual police cars the yellow paint is made of reflexes and reflect light, illuminating the car at night. Really cool!
Here is the original, for reference.

I thought it came out pretty good, what do you think? Also, If you would like to download it, you can find it under my GT, nVerdict.
