Regarding real time reflection, yes it is possible!
Add a Scene Capture Cube component to the vehicle actor.
Create a TextureRenderTargetCube on the content browser, and assign the Scene Capture Cube component to update that texture.
On the material, add the TextureRenderTargetCube and as its UVs, add a Reflection Vector node. Connect this texture to the material’s Emissive.
There is an example of this in the Content Examples, I think it’s on the Reflections map.
