First, thanks for the credit.
Second, and more important, try to only advertise your own products whenever you release something. It's ok to give credit whenever you're using only a small amount of other people's work, but when more than half of the work is someone else's then what's the point? It's almost like you're advertising someone else's stuff rather than your own stuff. Just my opinion. But I have no problem with you using my headlights, after all they are the best ever made in the past, present, or future lol!
Keep it up though, try to make your own headlights now, after all mine are from a BMW, which is not an American car. Try putting some Ford headlights or something. When you're done with that try doing the interior too.
