I'm going to buck the trend here, if it is a small town and you will see the guy a lot and people that will see your car will have seen the other guys car, I think I would not copy it. For this reason: It is a very prominent part of the car. It is the one thing that sets his car apart from the others. I think in this case you would be stealing his thunder a bit. On the other hand, if you saw the idea on the web or a t a small show miles away from home while on vacation or business, then copying it would not detract from his car. Normally I would say copy away but because of the close proximity of the cars and the uniqueness of the idea, I'd say congratulate him and forget it. Mart.
