The springs are ridiculously good! I think wiring the engine and photoetch seat belts would be as much as you’d need to add. As I don’t have an airbrush going at the moment, I’m swaying towards mica silver as it will lay on easier than the orange. The doors are a problem paint wise. For the model to look good, there’s a seam line that needs filling as the doors are constructed in 2 pieces. But this creates a painting nightmare. Nothing is perfect, but this kit is mighty close! Cheers.
