I will be doing a couple of reviews later in the week on two 1966 Chevrolet Nova Pro Stock Ertl Collectible cars.
Here are a couple of quick iPhone 8 Plus photos of the cars, the candy apple red with flames Nova has a working opening trunk out of the box, the black chrome Nova Ertl puts two round plastic dowel pins wedged into the "U" shaped hinges so the trunk won't open. All you have to do is remove six small screws on the bottom of the car one screw at each corner and one screw on the right and left side in the middle of the chassis and carefully remove the body from the chassis, then you push the round plastic dowels out from the hinges and the truck will open. I don't know why Ertl disabled the trunk when it has the hinges to make it open.
In my opinion this body style is the best looking Novas built.
