Guys, sorry about my abusive comment yesterday. I was blowing off some steam at the wrong people.
Shaunn, I don't know whether he thought that my car was premium or if the size is wrong. After re-reading the rules the only one that I broke was the 500px limit (which I still need to correct). The car is standard though although there are premium versions of it. You can see it's standard if you look closely at the tail lights.
JTSnoots, sorry for posting the abusive comment at you. You didn't deserve that. However, could you please tell me what rule I broke in case there's something else? That would be very helpful.
