Sweet, I couldn’t figure out how to add colour and ended up trying to photoshop it with real images from cars and took up wayyyyyyy too much time haha - so I settles for plain. Good job 
Awesome Work! Must have taken a long time
BTW how did you add colour?
in the Assets section of the editor right click on a open space then go create > material. Once the material is made click on it and go to the inspector and click on the color picker and choose the color you want. Then drag the material to what you wanted to color. The attached picture shows where to find the color picker in the inspector.
Thanks for the color explanation; I probably would have spent quite a while trying to figure it out.
