This is looking like a "Show Pershing"! I like it! When I look at the emblem you made, I think of "426 Hemi" instead of "M26 Pershing", haha. I think what you have done goes well with the Ford Muscle Car V8 sounds the Pershing makes. Although, I don't know if your exterior is going to look as "showy" as your interior, so it may look like two different tanks, outside versus inside.

I'd just leave the ground effects lighting and the racing stripes off of it when your done It could be one of those vehicles that is too nice to drive for fear of a rock scratching the paint job. Your interior keeps making me think of a tricked out show car when I look at it.. Everyone will know who's Pershing this is, won't be confused with anyone else's.
