Need help perfecting the budget build hemi swap

A friend on facebook sent the top photo of what is supposed to be GM's new Chevelle concept car. It's obvious the are trying to reuse the roof line from the Camaro, but it looks like ***. I'm no computer guru, but I grabbed a photo of a nice pro touring Chevelle, grafted on the new Camaro roof, fattened it up a bit and added ground effects in the front, and rear. Why is that so difficult for car companies to understand. Well, at least the people in the newly legal marijuana zones of Wash, and Colorado might tolerate GM's design studio with a little less uproarious fan fair. I hear they are going to revolt nationally for a free marijuana country, but first they need a little nap, and some munchies.
