I say keep it. Unless you need money or its becomeing a problem but other than that why sell it. Sure it may not be a gold mine like a copo is but look at regular 69 camaros. They are big $ now. How do you think they got that way? Sure its gona take time but if its not a prob why sell. It will still be a nice car just to ride around when you can.
Hell fear me! I am the one who will bring you down! And when you fall feel me! You'll see my face on the battle ground!
