It's strange that the front of the vehicle flickers like that. Perhaps that's just the main light. Unchecking (or checking) 'Visible in raytracing' doesn't matter unless you're using a raytracing light and asking Poser to render in raytracing mode.
The fire object is very good. Animated sprites can be useful in Poser, especially at our scale.
