I pruchased my turkey pan from Finishline, some time ago, too. It came pretty much looking the same as yours. I used some aluminum polish and a polishing wheel with a touch of elbow grease, and it came out looking fine. When I got it though, I was a little disappointed in the quality and was going to send it out to a professional polishing company, but decided I wanted to do it myself. I don't think the original cars had perfect and pristine turkey pans, so I thought, what the hay! I am going for that original look, afterall. In hind sight, I do wish I had ordered from Kirkham, though.

All thing considered, you can put together a pretty good argument that the 427 Cobra is the ultimate performance car, judged on any basis you want to name."
