Here's some minor mods to MP-10 I've done (I am a novice modeler, so nothing fancy!). I removed the wheel covers to give the legs a slimmer look and allow the wheels to be showing in robot mode (that screams G1 prime to me). The lack of wheel covers also makes keeping the legs together in truck mode a little less finicky. I also painted silver around the rear wheel fenders to match the front fenders I painted the cab lights (clear orange over silver to give it some depth). Might not be G1 cartoon accurate (which wasn't colored to match real-life vehicle colors, but rather to show up on screen better), but I also gave a more orange tint to the clear pieces on the waste and the accents on the forearms. I always thought these should have been similar in color to the orange lights on a real semi cab, since the original G1-transformation had the front bumper turn into the pelvis. I also like how the darker accent colors go better with the overall darker color scheme of the Takara MP-10, vs that nasty Mt. Dew lemon/piss yellow... just IMO.
