Pretty Good, but not perfect.
1st - matt parts are little too blue - real car is 100% grey (blue glow is caused by lighting aroud car),
2nd) only grey parts are matt but also not 100% (they are only much less reflexive than other coloured parts, but not 0% reflex),
3rd) other coloured parts have normal reflex like gloss painting.
4th) orange part in front of car is too square - in real this part is more rounded.
PS: If you want I can send you proper speccoc texture, which I made for my own use.
