I have read some of your threads and I know you are a "purist" who likes to make stuff look stock and there is nothing wrong with that. I have been impressed with some of your ideas and your work. But if you look at some of the brand new pontiacs on the road today, that is EXACTLY what they are doing (photo below), putting 3 badges on the rear, mixing fonts, and crowding one side which makes it look off center, along with crowding the entire rear end of the car - almost exactly like what FRANKAR15 did. So, technically, he is doing exactly what pontiac does.
I know everyone has his or her own personal taste and doing little things like this make each of our cars "our own" and we will not all agree on each others ideas, etc. Personally, I liked the idea so much I am doing the same to mine. Only, I put the GXP emblem just to the right of where it says Bonneville. So now it says BONNEVILLE GXP. I plan on removing the V8 emblem and putting a Northstar V8 badge there. I want people to know what it was that just passed them on the highway when I go by.
I don't think that Pontiac did a very good job of advertising that on the rear of this car, so I will take care of it myself on the one I own.
