I agree they look great and explored murals for my van. Ended up not going ahead based on one consideration from my painter. He suggested that murals only look their best when they are across a large portion of the body metal, and after thinking on it, i agreed, so opted out based on cost factors.

You see it in the article posted above, where the best looking vans have expansive artwork on them that covers rear, sides, doors and bonnet etc.
